Abstract
Disclosed are systems and methods which provide signal processing circuitry utilizing a variable gain transimpedance amplifier configuration which is economical to implement and which provides for power efficient circuit implementation. Preferred embodiments provide a transimpedance amplifier having an output intercept that remains constant while a corresponding input intercept increases as gain is reduced. An analog optical receiver preferably implements an architecture in which the variable gain transimpedance amplifier is disposed as an input amplifier.
