Abstract
A circuit including a power amplifier having a control terminal configured to control an output level of the power amplifier, a bias circuit in communication with the control terminal, the bias circuit including a tunable plurality of diodes in series configured to supply a bias voltage to the control terminal, and a control circuit in communication with the bias circuit configured to tune the plurality of diodes in series to create the bias voltage in response to a supply voltage of the amplifier.
