Boost-on-demand amplifier

摘要

A method and an amplifier for amplifying audio signals receive and process an incoming audio sample in preparation for amplification by an electronic amplifier circuit. A boost supply circuit receives a voltage from a power supply. A processor system determines whether amplification of the incoming audio sample warrants more voltage than the voltage received from the power supply. Before completing the processing of the incoming audio sample, the processor system sends a signal to the boost supply circuit to boost the voltage received from the power supply and to supply the boosted voltage to the electronic amplifier circuit if the incoming audio sample warrants more voltage than the voltage received from the power supply. Otherwise, the boost supply circuit passes the voltage received from the power supply to the electronic amplifier circuit.

1. A method for amplifying audio signals, the method comprising:
processing, by a signal processor, an incoming audio sample in preparation for amplification by an electronic amplifier circuit; receiving a voltage from a power supply; determining whether amplification of the incoming audio sample warrants more voltage than the voltage received from the power supply; before completing the processing of the incoming audio sample, boosting the voltage received from the power supply and supplying the boosted voltage to the electronic amplifier circuit if the incoming audio sample warrants more voltage than the voltage received from the power supply, and otherwise passing the voltage received from the power supply to the electronic amplifier circuit; and waiting a minimum period after supplying the boosted voltage to the electronic amplifier circuit before switching back to passing the voltage received from the power supply to the electronic amplifier circuit.
