It will discuss the motivation, the trade-offs involved and the key concerns that apply to the use of digital techniques in analog circuits We will look at a few illustrative examples and also discuss the challenges involved therein Srinadh Madhavapeddi is a Digital Design Lead in the Wireless Analog and RF Section of Wireless Business Unit of Texas Instruments He has been with TI for years and has most recently worked on Digital Signal Processing blocks like Decimation and Interpolation Filters for Sigma Delta Data Converters as well as Frequency Synthesizer loops He also works on Mixed Signal Methodology in areas like modeling of Analog circuits in HDL and Mixed Signal Design for Test (DFT Previously he has worked on System on Chip (SOC) designs in the Connectivity business including Ultra Wideband Baseband, PCI-Express Switch and Bridge products as well as 1394 Link Layer devices Srinadh obtained an MSEE from the Johns Hopkins University in Baltimore, MD where he was a student of Prof Gert Cauwenberghs He has filed three patents with the USPTO and has published both conference and journal papers
