Accurate noise characterization of MESFETs and HEMTs is required for the design of high‐frequency optical receivers. Here we consider a technique that extracts the intrinsic noise parameters P, R, C from measured noise data. Novel analytic expressions are presented as well as results that prove the validity of the technique. © 1993 John Wiley & sons, Inc.
