ABSTRACT:
The present invention is directed toward a system and apparatus for digitally controlling a bias control signal for at least one transistor. The present invention provides for software writable registers that control the bias control signal. The present invention further provides for the bias control signal to be temperature compensated based upon a temperature signal and a temperature profile stored in software writable registers. The present invention further provides for software control of the initialization and configuration of the bias control signal through stored program control of the values in the software writable registers.
