Synthesis Of A Translinear Analog Adaptive Filter, Eric Mcdonald, Bradley Minch
Bradley Minch
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 ina 0.5-μm double-poly CMOS process.

Floating-Gate Techniques For Assessing Mismatch, Bradley Minch
Bradley Minch
I discuss the importance of capacitor matching in the context of using charge stored on floating-gate MOS (FGMOS) transistors to compensate for transistor mismatch in analog circuits. I describe a simple technique that only involves static measurements for assessing the relative mismatch between capacitors. I also show experimental measurements of capacitor mismatch for small capacitors fabricated in 1.2-μm and 0.35-μm double-poly it n-well CMOS process that are commonly available.
