Abstract
A switching amplifier includes a first half-bridge PWM modulator, a second half-bridge PWM modulator, and at least one amplifier stage configured to receive input signals. The switching amplifier also includes a PWM control stage configured to control switching of the first PWM modulator and of the second PWM modulator as a function of the input signals, by respective first PWM control signals and second PWM control signals. The amplifier stage and the PWM control stage have a fully differential structure.
