Kian Hamedani (advisor: Yi, co-advisor: Liu) successfully defended his Ph.D. dissertation entitled “Energy Efficient Deep Spiking Recurrent Neural Networks: A Reservoir Computing-Based Approach” on May 12, 2020. His dissertation research includes: 1) inspired by delayed feedback reservoirs, spiking recurrent neural network, named SDFR was introduced which was both easy to train and energy efficient. 2) The effectiveness of this model was evaluated in solving different problems, namely, attacks detection in smart grids, MIMO-OFDM spectrum sensing, and video-based face recognition. Moreover, the model was extended in space to capture the spatial correlation as well.  3) For the first time, cGANs were combined with SDFR to solve the data scarcity problem of AI enabled MIMO-OFDM spectrum sensing. Multiplexing different neural codes which is inspired from rats was formulated and implemented which leads to more robustness against noise and adversarial attacks. 4) Finally, for the first time, it was shown that increasing the membrane capacitance of a spiking neuron (up to a certain point) can strengthen the resilience of SDFR against adversarial attacks. Kian joined the MICS group after an MS degree from Tehran Polytechnic, Tehran, Iran, and will join industry. We wish Kian good luck in his industry career!

long

Long Huang (advisor: Raman) sucessfully defended his MS thesis entitled “Linearized 4 – 7 GHz LC Tunable Filter with Active Balun in 0.18um SiGe BiCMOS” on May 11, 2020. His thesis presents the design and comparison of two active balun (single-ended to differential-ended converter) topologies to drive a parallel synthesis LC tunable filter. The application of active balun replaces the combination of passive balun plus the transconductors at the input circuitry of the filter. Second order intermodulation distortion injection and noise-distortion cancellation topologies are applied to linearize the baluns. The goal is to reduce third order intermodulation distortion and keep noise figure in acceptable range. Detailed designs and analysis, especially Volterra analysis, of these baluns is carried out to predict the performance. Predicted performance of parallel synthesis LC tunable filters implemented with the active baluns shows to be competitive with state of the art integrated filters. Long received a BS degree from Virginia Tech, and will join Northrop Grumman. We wish Long good luck in his industry career!

Kanika Saini defended

Kanika Saini (Advisor: Raman) successfully defended her Ph.D. dissertation entitled “Linearity Enhancement of High Power GaN HEMT Amplifier Circuits” on August 8th, 2019. GaN (Gallium Nitride) technology is emerging as a technology of choice for radar and wireless applications. It provides high output power and high breakdown. With the advent of 5 G technology, the amplifiers in the T/R (Transmit/ Receive) module need to be more linear to handle signals with high PAPR (Peak to peak Average Power Ratio). Her dissertation demonstrates linearity enhancement of GaN amplifier circuits by using multiple independently biased parallel FETs. Linearity improvements have been shown for both GaN PA (Power Amplifier) and GaN LNA (Low Noise Amplifier) circuits for the first time using GaN FETs (Field Effect Transistors). A computer-aided design methodology has been developed to facilitate the design of such circuits. This concept has also been illustrated for an X band GaN MMIC (Monolithic Microwave Integrated Circuit). The technique is low cost and simple to implement. Kanika joined the MICS group after completing her Masters from Punjab Technical University (PTU) and working as an assistant professor in Lovely Professional University (LPU), India. She is currently working in AMCOM Communications, Gaithersburg, MD. We wish Kanika good luck for her future endeavors.

Park PhD Defense

Shinwoong Park (advisor: Raman) successfully defended his Ph.D. dissertation entitled “Reconfigurable Discrete-time Analog FIR (AFIR) Filters for Wideband Analog Signal Processing” on January 14, 2019. His dissertation research includes: 1) A 3.25GS/s 4th order Analog FIR filter design, 2) Implementation of FIR-based beamforming, and 3) Analysis and optimization of multi-section capacitive DACs (digital to analog converters).

Brian Worek defended an MS thesis and plans to join industry (December 2018)

Worek MS Defense

Brian Worek (advisor: Ampadu) successfully defended his MS thesis entitled “Enabling Approximate Storage through Lossy Media Data Compression” on December 13, 2018. Memory capacity, bandwidth, and energy all continue to present hurdles in the quest for efficient, high-speed computing. Fortunately, many memory-bound applications demonstrate inherent error resilience, a property that allows them to produce acceptable outputs even when data used in computation contain errors. Approximate storage exploits this property to improve memory energy consumption and performance through quality-energy scaling. His thesis reviews state of the art approximate storage techniques across circuits, architectures, and algorithms before presenting a lossy memory compression algorithm to enable approximate storage. Simulations with image data show the algorithm increases effective storage capacity by 15% and subsequently off-chip memory access energy costs by 15% for only 3% accuracy loss in an image classification application. The total energy overhead of the design simulated in hardware is less than 0.1%. Brian received a BS degree from Virginia Tech and will join Google as a hardware engineer. We wish Brian good luck in his industry career!

Shuang Cheng defended on MS thesis and plans to join industry (December 2018)

Shuang Defense

Shuang Cheng (advisor: Yi Yang) successfully defended her MS thesis entitled “Two-Phase Buck Converter Optimize by Echo State Network” on December 11, 2018. Echo State Network(ESN) is one of the main types of reservoir computing. The main benefit of ESN is that training is performed only at the readout stage and the reservoir is fixed. Connect ESN with two-phase buck converter can improve the efficiency and save more simulation time. The design changes the period of two-phase buck converter from 40µs to 100µs, compare the results with two-phase buck converter and ESN. Turns out the ESN save more time on simulation and can get a higher efficiency when the period of the switch is high. Shuang Cheng received a BS degree from Virginia Polytechnic Institute and State University and will join the industry. We wish Shuang good luck in her industry career!

Kanika Saini wins 3rd prize in the student paper competition at IEEE WAMICON (May 2018)

Saini 3rd Prize

Kanika Saini (Advisor: Raman) won 3rd prize in the student paper competition held at 2018 IEEE Wireless and Microwave Technology Conference, Sand Key, FL, April 9th and 10th,  for her paper titled “S-Band GaN LNA with OIP3 >50dBm using parallel independently biased gates”. As spectrum becomes more congested, it is becoming imperative for communications, radar, etc. T/R module amplifiers to be more linear to handle the more challenging interference environment. GaN technology is becoming more heavily used in such applications, and innovative approaches are needed to improve the linearity of GaN-based amplifier circuits.

His dissertation presents designs of a transimpedance amplifier for the data rate of 100 Gb/s and a clock-recovery circuit for the data rate of 40 Gb/s. The input resistance of the TIA amplifier is lowered through adoption of a diode-connected transistor at the input stage, and a test chip fabricated in 32 nm SOI CMOS technology achieves the bandwidth of 74 GHz to enable the data rate of 100 Gpbs. The clock recovery circuit employs a resonator-based frequency-doubling scheme.

Cascade Falls

MICS people enjoyed hiking along Little Stony Creek to Cascade Falls and cook out on April 28. Cascade Falls in Jefferson National Forest is one of the most beautiful waterfalls in Virginia and possibly on the entire East Coast. Several streams cascade on the way down while others fall the whole distance of the falls. MICS people cooked out at the state park after the hike. They enjoyed the beauty of sprouting trees and wild flowers of spring as well as foods, drinks, and, equally as important, the relaxed atmosphere at the end of the spring semester. MICS people work hard, but remember there is life outside of work!
