Show morePower amplifier (PA) is the most important circuit block in an RF transmitter. It typically consumes more than 80% of the power taken by the entire transmitter. Therefore, a highly efficient PA is the key to a successful RF front-end system. The polar transmitter architecture is studied herein in order to take advantage of the highly efficient switching-mode PA. However, due to the large expanded bandwidth from the nonlinear IQ to polar conversion and the sensitive amplitude/phase delay impairment, hardly any reported polar design is able to transmit high data rate wireless communication signals. In this work, an extensive research on the digital polar transmitter system for high data rate signals is presented. An integrated CMOS digital power am- plifier (DPA) design is demonstrated afterwards. This DPA consists of 9-bit fully thermometer-coded uniform cells to achieve high linearity for wide bandwidth OFDM signals. By analyzing the amplitude and phase paths impairment, which will cause both in-band and out-of-band distortions, a 960 MHz digital delay tuner is designed for precise amplitude and phase alignment. Furthermore, two digital pre-distortion algorithms for DPA are implemented and compared. Importantly, an on-chip DC- DC converter is included for direct battery connection and power control. A boosted cascode gate bias improves PA efficiency at the low power region. The proposed design is fabricated using a 55 nm RF CMOS technology. The DPA with several peripheral blocks occupies only 0.63 mm2 active silicon area. This DPA including the digital AM filtering achieves a peak output power of +21.9 dBm with 41% efficiency. It achieves EVM of 2.9% with 20 MHz IEEE 802.11ac compliance of 256-QAM OFDM signals, and also achieves EVM of 4.5% (CC0) / 4.8% (CC1) with 2 x 20 MHz 3GPP LTE-Advanced carrier aggregation compliance of 64-QAM OFDM signals. This highly linear DPA has demonstrated high flexibility, high efficiency, and small area. To the author's knowledge, this is the first reported DPA that meets either the linearity requirements of 256-QAM OFDM signals or the signal bandwidth of 40 MHz, paving the path for wideband high data rate wireless applications using digital polar architecture. At the same time, aiming at a higher average efficiency, a two-level class- G supply modulator is investigated to dynamically switch the DPA VDD. It has successfully demonstrated an average efficiency of 34.6% for this class-G modulated DPA in a complete circuit simulation using the IEEE 802.11b signal.

Show moreStudents will continue the work of previous IPRO teams to convert a Quicksilver MXII ultralight airplane to run on E85 fuel (85% ethanol, 15% gasoline). This is technically challenging because the plane uses a 2-stroke Rotax 503 engine, where the oil must be mixed in with the fuel. After the conversion, the plane will be flight-tested. In the mean time, the plane can be flown by students to enjoy the experience of flying a personal-type aircraft. In addition to the technical aspects, the project involves developing and maintaining relationships with sponsors, public relations, and a study of the potential for ethanol in the ultralight aircraft market. This project may eventually lead to the creation of a student organization responsible for maintaining and flying the ultralight aircraft.

Show moreA subharmonic noise reduction circuit having an input terminal and an output terminal. The circuit has a first differential amplifier with a first non-inverting input, a first inverting input and a first output. The overall circuit input terminal is connected to the first non-inverting input. A low-pass filter is connected between the first output and the first inverting input. A second differential amplifier has a second non-inverting input, a second inverting input and a second output. The second output is connected to the overall circuit output terminal. A first resistor is connected between the second output and the second inverting input. A second resistor is connected between the first non-inverting input and the second non-inverting input. The circuit operates at unity gain of the DC voltage component and thus the DC output voltage follows the DC input voltage.

Show moreIndia’s huge and growing population is putting severe strain on all of the country’s natural resources. Most water sources are used on a domestic, industrial and agricultural basis. The quality of the water used is presumed to be the major problem that the people face, but the real problem is the quantity of water supplied. Quite a few organizations have been engaged with supplying drinking water to the community, but still not enough to address the needs of all the different sectors of the community, especially irrigation. In order to increase the availability of water to the people, it is necessary that the people have alternative means of supply of water, and a strong sense of the value of water.

Show moreChicago is the third largest intermodal freight hub in the world. As a result, there is need for efficient routing of trains throughout the Chicago area. One aspect of railroad transport that directly affects the overall efficiency of the rail system is how easily accessible train intermodal yards are for trucks going to and through the intermodal yards. With this in mind, the overall purpose and objective of IPRO 307 is to improve the truck flow in and around an intermodal facility at Harvey, IL which is owned by Canadian National (CN) lines. CN is one of the six major railroads that serve the Chicago area. The intermodal facility at Harvey is surrounded by a network of highways including Interstates 80, 57, 294, 94 and 65. Interstates 294 and 80 cross directly overhead of the intermodal yard. In order to make truck flow around the intermodal yard more efficient, IPRO 307 will look into the addition of ramps and frontage roads, including a ramp that would be based off of interstates 80/294. A ramp connecting the major interstate to the intermodal facility would allow for easier access to the intermodal facility by trucks, thereby bettering the efficiency of the intermodal facility as a whole.

Show moreThe ultimate goal of the Zero Energy Lab is to get the fourth level of machinery hall off the electrical grid. The IPRO is moving towards transforming the space into a research space for future energy and lighting technologies. Since the end goals of the Zero Energy Lab are ambitious for one semester we are proposing to address solar hot water, a golf cart used as a mobile battery bank, and window efficiency this semester. We are also hoping to learn some tuck-pointing techniques to make the space more presentable. We would like for the team to learn new things about the technologies we are researching and using. We hope to have a good hands-on experience with energy efficiency and green technologies. The team is a collaboration of students from various majors including architecture, political science, civil engineering, electrical engineering, mechanical engineering, and biophysics. Together we believe we will be able to create a cohesive end product and work well together along the way.

Show moreThis research's purpose is to optimize an existing method to simulate stochas- tic integrals using Monte Carlo when the cost of function evaluation is dimension dependent. In the area of mathematical nance, we often need to price a path- dependent nancial derivative. This will result in the computation of E[g(B( ))], where g stands for a payoff function, and B is the Brownian Motion. A simple way to approximate this expectation is to take the average of the functional over a large num- ber of sample paths. Each path is approximated by a d-dimensional random vector. A larger d will provide a more accurate result. However, due to the limitation in time cost and computer memory, some large dimensions are not easy to be implemented. Therefore, we introduce the multi-level technique that is based on multi-grid ideas. It can be used to reduce the computational complexity for these kind of problems. Moreover, when we apply the multi-level technique, the proper sample size for each subspace integration needs to be computed in order to satisfy our guaranteed conser- vative xed width con dence intervals. Thus, the automatic sample size algorithm (two stage con dence interval algorithm) is used in conjunction with the multi-level method.

We’re working with the Brookfield Zoo education staff and animal researchers to develop a guided inquiry process that will assist users in finding and identifying animals. Getting closer to an animal is a breeze. Because the animals’ locations are mapped, you can find them easily on foot or identify them by their color, pattern, and shape. Learn fun facts about any animal you choose while watching videos and scrolling through pictures. We’re working to create the best tour guide for the zoo that fits in your pocket.
