Abstract:
Resistivefeedback DACs (an alternative to current-steering DACs) present an interesting choice in continuous-time delta-sigma ADCs due to their low noise, low-supply operation, and simplicity. However, this seemingly nifty architecture presents unique mechanisms that cause distortion and spurs at the ADC output. Some of these are presented in this talk, along with methods to address them, in the context of a 76.8-MS/s, 1-MHz-bandwidth continuous-time delta-sigma ADC targeting >90dB SFDR, developed for integrated narrowband direct-conversion transceiver applications.
Biography:
Sharvil Patil received the B.E. degree (Hons.) in electrical and electronics engineering from the Birla Institute of Technology and Science, Pilani, India, in 2009, and the M.S., M.Phil., and Ph.D. degrees in electrical engineering from Columbia University, New York, NY, USA, in 2012, 2016, and 2017, respectively.
From 2010 to 2011, he was with ST Microelectronics, India, where he designed high-speed digital-to-analog converters. He interned at CEA-LETI, Grenoble, France, in the summer of 2013, investigating event-driven signal processors for wake-up receivers. He joined Analog Devices, Inc., Toronto, Canada, in 2016, where he works on high-speed analog-to-digital converters. His research interests include data conversion, analog and digital signal processing, and mixed-signal circuit design.
Dr. Patil received the Analog Devices Outstanding Student Designer Award at Columbia University in 2014.
