Receiver characterization using periodic small-signal analysis

Abstract

Periodic small-signal analysis is a recently developed approach for AC and noise analysis of linear periodically-varying circuits. This paper presents several new approaches to characterizing the transfer functions, noise, and distortion of communication circuits using this new technique. A receiver is used as an example, but the techniques presented are applicable to a wide variety of circuits, including mixers, samplers, sample-and-holds, chopper-stabilized amplifiers, multipliers and switched-capacitor filters.
