Abstract
An amplifier system can include a biasing amplifier that provides a first amplified signal to a DC blocking element that is connected with a load based on a first control signal. A power amplifier provides a second amplified signal for driving the load based on a second control signal. A control system controls the biasing amplifier to charge the DC blocking element so as to mitigate a voltage drop across the load (e.g., to substantially eliminate audible artifacts) when the power amplifier is activated to provide the second amplified signal.
