ABSTRACT:
A biasing system for a differential amplifier includes an NMOS current source and a gate bias voltage generator. The gate bias voltage generator produces a bias voltage VNCS to control the NMOS current source. The gate bias generator includes a reference current generator to produce a reference current relatively independent of supply voltage variations. A temperature compensator regulates the reference current to provide a temperature compensated current. A current mirror duplicates the temperature compensated current to a bias voltage generator. The bias voltage generator generates the bias voltage.
