Venue: C-DAC Bangalore

C-DAC's Advanced Computing Training School (ACTS) in Bangalore has emerged as a premier institute in designing and delivering industry relevant courses in Chip Design and Embedded Systems.

On July 04, 2002, ACTS Bangalore organized the first in the series of seminars on "Mixed Signal Design". A Mixed Signal Designer needs to constantly update himself to the technology options, tools for analysis, building blocks, analysis of non-ideal effects of Active devices used, sensitivity of the realized circuits to process tolerances, noise analysis & analysis of other non-idealities and scaling for optimal dynamic range amongst others. The seminar covered these areas in great detail. The seminar contents included: Introducing typical Mixed Signal Design candidates such as PCM filters, DTMF receivers, ADSL front-ends and so on; Basics of filter design; Technology options in brief: Active RC filters, Active R filters and MOSFET-C filters; Switched-Capacitor filters: Design of Biquads, First-order filters, Basics of DSP as needed, Ladder filters and other applications; Current-mode filters: OTA-C filters, Current conveyor based filters and CFOA based filters; Brief Introduction to Switched-Current Filters; Brief Introduction to Log-domain filters; Tuning issues in continuous-time filters; Sigma delta converters and Digital Decimation filters to realize practical systems; Design issues involving both digital and Analog circuits on the same chip.

The seminar speaker - Dr. P.V. Ananda Mohan, is a recognized authority in the area of Military Encryption Systems.

The seminar was attended by System Engineers, Digital Design Engineers, Project Leaders, Modeling Engineers, Analog Design Engineers and CAD Engineers.
