Abstract
A method and circuit for providing a bias voltage to a MOS device is disclosed. The method and circuit comprise utilizing at least one diode connected circuit to provide a voltage that tracks process, voltage and temperature variations of a semiconductor device. The method and circuit includes utilizing a current mirror circuit coupled to the at least one diode connected circuit to generate a bias voltage for the body of the semiconductor device from the voltage. The bias voltage allows for compensation for the process, voltage and temperature variations.
