Dr. Suman Sah

Dr. Suman Sah has harbored a deep fascination for mathematics and physics since his childhood. His intricate interest in radios and computers, combined with a hobby in astronomy, set the stage for an exceptional career.

He earned his Bachelor's and Master's degrees in Engineering from the esteemed Indian Institute of Technology, focusing on telecommunications, VLSI, and computer science. His passion for programming was evident as he enjoyed working with the 8086 microprocessor, using assembly language similar to that employed in the International Space Station.

Dr. Sah pursued his PhD at Washington State University, delving into analog and RF circuit design. His research encompassed voltage-controlled oscillators, phase-locked loops, injection-locked ultra-low-power oscillators at mm-wave frequencies, and various RF frontends, including LNAs, VGAs, phase shifters, and mixers. His innovative work earned him three patents and numerous publications in top-tier journals and conferences.

Professionally, Dr. Sah has extensive experience in phased array radar design in silicon, understanding the associated challenges. He contributed to the design of one of the first commercial full-duplex radios for cable and developed Ku/Ka band phased arrays for satellite applications. His expertise in RF frontends for wireless backhaul has resulted in solutions that meet the evolving demands of fronthaul and backhaul networks for 4G and 5G cellular networks.

Dr. Sah's technical prowess extends to designing ultra-low-power receivers for DOCSIS battery backup mode, ultra-high-performance digital-to-analog converters (DAC) for RF synthesis bandwidth over 850 MHz with SFDR > 80 dBc, and high-performance analog-to-digital converters (ADC) for 100GHz SERDES. He also has significant experience with high-performance delay-locked loops for precise quadrature generation.

In the analog domain, Dr. Sah has worked on bandgap design, low-dropout regulators, PTAT circuits, high-accuracy temperature sensors, baseband filters, biquads, notch filters, and transimpedance amplifiers.

Dr. Sah enjoys programming and automating various stages of RF design. Through his company ModAnalog, he released a fully functional RF inductor synthesis tool. Currently, he focuses on providing custom design services in analog circuits and RF design across various technologies. His approach ensures first-silicon success for early sampling and reduced lab or testing time through on-silicon automation. Quick turnaround is achieved through process-independent methodologies and modular design.
