Abstract: Certain aspects of the present disclosure generally relate to electronic components and, more particularly, to circuitry for signal amplification for transmission. One example apparatus generally includes: a modem; a controller; a feedforward path coupled between the modem and the bias controller; and an amplifier having a main amplification path and an auxiliary amplification path, wherein the controller is configured to provide at least one bias signal for biasing the auxiliary amplification path based on information associated with a transmission signal, the information being provided by the modem to the controller via the feedforward path.
