Frequency Domain Stability Criteria for Large-Signal Tuned Common-Base Amplifiers

The purpose of this paper is to present a rigorous derivation of design criteria which ensure the stability of tuned large-signal common-base amplifiers. Utilization of the Sandberg-Zames circle criterion for stability investigations of nonlinear sytems coupled with an intertwining of the charge storage and excess phase models for a transistor, generates results which disclose the minimum and maximum rate of change of base-to-emitter voltage commensurate with unconditional stability.
