ABSTRACT: We review our work on circuits and systems that combine more than one domains of operation. The first systems to be discussed are digital signal processors in which the binary waveforms used are functions of continuous time, with no sampling. These processors have no aliasing and no quantization error at frequencies that are not signal-related. Also to be discussed are input-output linear analog filters which are internally nonlinear, and processors in which digital waveforms are processed directly with analog circuits. The talk will conclude with a description of analog VLSI computers, which make approximate computation faster, and which can co-operate with digital computers to speed up accurate computation.
BIO: Yannis P. Tsividis is Charles Batchelor Professor of Electrical Engineering at Columbia University in New York. Starting with the first fully-integrated MOS operational amplifier, which he demonstrated in 1976, he has done extensive work in analog and mixed-signal integrated circuits at the device, circuit, system, and computer simulation level. He is the recipient of the 1984 IEEE W.R.G Baker Best Paper Award for the best IEEE publication, the 1986 European Solid-State Circuits Conference Best Paper Award, and the 1998 IEEE Circuits and Systems Society Guillemin-Cauer Best Paper Award. He is co-recipient of the 1987 IEEE Circuits and Systems Society Darlington Best Paper Award and the 2003 IEEE International Solid-State Circuits Conference L. Winner Outstanding Paper Award. He is a Fellow of the IEEE. Among his teaching awards are Columbia’s 2003 Presidential Award for Outstanding Teaching, and the 2005 IEEE Undergraduate Teaching Award.
