Abstract

A high swing cascode bias circuit is provided for use within an integrated circuit. The bias circuit utilizes a start up transistor. The use of the start up transistor allows for high swing at the bias circuit outputs even though only one current source is provided from a reference bias circuit. The bias circuit may be powered down in response to a power down control signal. When the bias circuit is activated a plurality of bias signals may be provided to operating circuits of the integrated circuit.
