Abstract:
A signal amplifier includes a pulse width modulator, a level shifter, and a power amplifier. The pulse width modulator is driven by a positive power supply and a negative power supply, and a reference voltage of the pulse width modulator is set to a GND. The power amplifier is driven by a positive power supply, and a reference voltage of the power amplifier is set to a middle value between the positive power supply and the GND. The level shifter shifts a voltage level of a first PWM signal whose high level corresponds to the positive power supply of the pulse width modulator and whose low level corresponds to the negative power supply of the pulse width modulator, to a voltage level of a second PWM signal whose high level corresponds to the positive power supply of the power amplifier and whose low level corresponds to the GND.

Claim (Index 2):
The signal amplifier according to  claim 1 , further comprising an error amplification unit to which the analog input signal is input and to which the analog output signal output from the signal output unit is input by being fed back,\n wherein the error amplification unit outputs an error amplification signal that is generated by amplifying an error component between the analog input signal input to the error amplification unit and the analog output signal fed back and input to the error amplification unit, and the pulse width modulator outputs the first PWM signal having a pulse width corresponding to a signal level of the error amplification signal.
