A systematic approach to the analysis of noise in mixers

Abstract

A theory for the analysis of noise performance in active mixers is presented. An implementation of this theory using current simulation tools, as well as a more numerically efficient and accurate method, is included. The theory is used to analyze the noise figure of a 1-GHz monolithic mixer and agrees well with measured values.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
