Abstract
A circuit includes a signal modification circuit, a power stage circuit, and a boost converter circuit. The signal modification circuit generates a modified signal according to an input signal. The power stage circuit is electrically coupled to the signal modification circuit and receives a first voltage to amplify the modified signal and generate an output signal. The boost converter circuit selectively controls the amplitude of the first voltage. The signal modification circuit electrically coupled to the boost converter circuit. Therefore, the signal modification circuit is configured to dynamically adjust its own gain corresponding to the value of the first voltage, and the input signal is modified into the modified signal based on the gain of the signal modification circuit.
