Abstract
Provided is a power consumption control circuit, an amplifier circuit and a power consumption control method which control the power consumption associated with an amplification action in real time. A power consumption control circuit of the present invention comprises: a detection means which detects the presence or absence of an input of a digital input signal, spending a first period of time; a signal delay means which delays the digital input signal by a second period of time equivalent to the first period of time, and outputs the delayed signal; a digital-to-analog conversion means which converts the delayed signal into an analog signal, and outputs the analog signal; an amplification means which generates an amplification action when a bias is applied to it; and a bias control means which applies a bias to an amplification device, on the basis of a detection result obtained by the detection means.
