Abstract :
In this paper, we present a methodology for synthesizing analog systems using a class of circuits called dynamic translinear circuits. We illustrate this method by synthesizing part of a Least-Mean-Squares (LMS) adaptation algorithm used in an analog adaptive filter. We present preliminary experimental results from a chip fabricated in a 0.5-μm double-poly CMOS process.
