Matthew Belz

I am a Ph.D. student at the University of Michigan, where I study Electrical and Computer Engineering and am advised by Dr. Michael Flynn. I graduated from The Ohio State University and was fortunate to be a member of the Circuit Laboratory for Advanced Sensors and Systems, advised by Dr. Waleed Khalil. I recently worked in the SoC lab at NASA JPL developing integrated circuits for space sensing.

My research interest is the intersection of mixed signal and RF circuit design and the development of high-speed integrated circuits--specifically PLL and ADC design. I am also interested in the development of design automation to assist analog designers as transistors become less predictable analytically. My undergraduate honors thesis examined the development of a 28 GHz wide tuning-range LC-VCO for use in 5G designs.

This paper presents an integrated outphasing transmitter based on a fully-digital architecture and implemented in a heterogeneous process technology. The transmitter consists of four independent channels having CMOS phase modulators driving digital GaN PAs. For multifunction operation, multiple channels are combined off-chip, with in-phase combining for high-power telemetry signals and outphasing used for amplitude-modulated communications signals. The full paper is not public release (US Persons only), only this abstract was cleared for release.

Battery Analysis Device
Matthew Belz, 2016


Designed a precision data aquistion system with programmable load and charging to determine the health of LiFePO4 battery cells. Started as a hobby project and then was funded by Ohio State through the STEP program, which graciously provided funding for necessary test equipment and manufacturing.

Efficient Multi-Bit Neural Networks
Matthew Belz, 2018


Final project for ECE 5194.08--VLSI Digital Signal Processing Systems. I reviewed the current techniques used for neural net hardware acceleration and a proposed an extenstion of a hardware accelerator used for binary neural networks for ternary and two-bit networks.
