Analog VLSI signal processing: why, where, and how?

摘要: Analog VLSI signal processing is most effective when precision not required, and therefore an ideal solution for the implementation of perception systems. The possibility to choose physical variable that represents each allows all features transistor be exploited opportunistically implement very dense time- amplitude-continuous cells. This paper describes a simple model captures essential transistor. symmetrical also supports concept pseudoconductance which facilitates linear networks transistors. Basic combinations transistors in current mirror, differential pair, translinear loop are revisited as support material description variety building blocks. These examples illustrate rich catalogue nonlinear operators available local collective analog processing. difficult problem storage addressed briefly, well various means implementing necessary intrachip interchip communication.
