Summary:PURPOSE: A D-class amplifier is provided to use a second capacitor as an auxiliary power by properly controlling the conduction and non-conduction state of 6 switches. CONSTITUTION: A D-class amplifier circuit(100) comprises an output unit(101), a gate driver(102), and a PWM(Pulse Width Modulation) signal generator(103). The PWM signal generator generates a pulse signal in response to an input signal. The gate driver supplies a gate control signal to each gate of a transistor in response to the pulse signal. The gate driver includes circuit such as a level shifter to ramp up and down the level of the gate control signal.
