Abstract
A signal amplifier includes a modulator circuit, a power converter and a H-bridge circuit. The modulator circuit generates a first logic signal by comparing an input signal with a first waveform and generates a second logic signal by comparing the input signal with a second waveform. The power converter provides a first voltage and a second voltage. The H-bridge circuit has a first input terminal to receive the first voltage, a second input terminal to receive the second voltage and a pair of output terminals for providing an output modulated voltage to a load. The H-bridge circuit generates the output modulated voltage using a primary modulation when the second logic signal is in a first logic state and using a secondary modulation when the second logic signal is in a second logic state.
