Abstract

A boosted high gain, very wide common mode range, self-biased operational amplifier comprising complementary differential transistor pairs biased by biasing transistors and current mirrors, and comprising two amplifiers, each connected to bias an output cascode transistor so as to provide a very high amplifier output impedance, wherein the biasing transistors and current mirrors are all self-biased via negative feedback.
