Signal Processing blocks in Analog Circuits for deep submicron technologies
by Srinadh Madhavapeddi Texas Instruments, Inc
Dallas, Texas
Abstract: When we think of traditional circuits like data converter (DAC and ADC)
circuits, Phase locked loops or High Speed Serial Transceivers; we associate these to be in the Analog circuit design domain While this is true, what is also happening is that as technologies shrink, the cost of integrating more digital gates has reduced even as the variation of Analog components becomes a bigger concern These two factors mean that the use of digital gates as a means of correction/compensation up-front or post processing
is becoming more common place
This seminar will focus on the “digital inside Analog”! 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 9 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
