Abstract
An apparatus and method is disclosed for providing a mirror circuit for detecting a change in current of a RF power amplifier. The mirror circuit includes a voltage operably coupled with the mirror circuit, a bias circuit operably coupled with the mirror circuit, wherein the bias circuit is capable of applying a bias voltage to the mirror circuit, and an output reference signal. The output reference signal is proportional to the change of current in the RF power amplifier.
