Abstract
A power amplifier () for a transmitter circuit () is disclosed. The power amplifier () comprises at least one field-effect transistor () having a gate terminal () and a bulk terminal (), wherein the at least one field-effect transistor () is configured to receive an input voltage at the gate terminal () and a dynamic bias voltage at the bulk terminal (). Furthermore, the power amplifier () comprises a bias-voltage generation circuit (). The input voltage is a linear function of an input signal. The bias-voltage generation circuit () is configured to generate the dynamic bias voltage as a nonlinear function of an envelope of the input signal.
