Amplification control circuit and amplification control method

Abstract

An amplifier control circuit includes a first bias unit and a second bias unit. The first bias unit outputs a first current to a first amplifier. The first bias unit includes a primary bias circuit and a preheat signal generation circuit. The primary bias circuit receives an operational voltage signal, outputs the first current and outputs a detection signal. Change of the operational voltage signal is related to change of the detection signal. The preheat signal generation circuit generates a preheat control signal according to the change of the detection signal. The second bias circuit outputs a second current to a second amplifier. The second current in a first period is larger than the second current in a second period. The first period starts after the operational voltage signal starts to change, and the second period starts after the first period ends.
