Process and Temperature Compensation for RF Low-Noise Amplifiers and Mixers

Abstract

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Temperature and process variations have become key issues in the design of integrated circuits using deep submicron technologies. In RF front-end circuitry, many characteristics must be compensated in order to maintain acceptable performance across all process corners and throughout the temperature range. This paper proposes a new technique consisting of a compensation circuit that adapts and generates the appropriate bias voltage for LNAs and mixers so that the variability with temperature and process corners of their main performance metrics (S-parameters, gain, noise figure, etc.) is minimized. </para>
