The thrust to integrate more features on a single die has made system-on-chips (SoCs) increasingly complex. These SoCs routinely deploy several data converters together with digital backend to realize single chip solutions for both established and upcoming applications e.g. Automotive Radar, LiDAR, and 5G. Essentially, SoCs are the new-era PCBs integrating analog/mixed-signal IPs with complex digital signal processing engines. Omni Design Technologies (Omni), Inc. is a developer of disruptive analog/mixed-signal IP cores with the mission to provide a wide range of low-power, high-performance embedded circuits for system-on-chip (SoC) development. In this presentation, I will first introduce Omni followed by a brief overview of our IP portfolio and targeted application space e.g. 5G, LiDAR among others. I will then walk you through our LiDAR solution followed by salient details and measurements results of our 10-b, 2.5GS/s ADC, and 12-b, 7GS/s DAC, both designed in advanced FinFET processes. I will conclude with brief descriptions of our propriety SWIFT™ technology and notch-less time interleaving background calibration.

Speaker Bio:
Dr. Vaibhav Tripathi received PhD and MS degrees in Electrical Engineering from Stanford University and B. Tech in Electrical Engineering from Indian Institute of Technology (IIT), Kanpur. He has been with Omni Design since 2018, where he is now the Vice President of Technology. In 2010, he was with Texas Instruments, Dallas, working on high-speed comparators. From 2014-2016, he worked in the high-speed data converters group at Maxim Integrated, where he developed a low-power 14-b, 250 MS/s pipelined-SAR ADC. From 2016-2018, he was with Samsung Semiconductor, where he co-led the development of 10-b, 2GS/s time-interleaved SAR ADC. In addition, he was also involved in several RF projects such as low-power BLE receiver for IoTs and MM-Wave phase shifters for 5G. Dr. Tripathi is a recipient of the Stanford Graduate Fellowship and Analog Devices Outstanding Student Designer Award 2013, and his research interests include high-speed data converters and RF/MM-Wave frontends.
