  • Switching amplifier system with feedback
    Patent number: 11848651
    Abstract: A switching amplifier system with a power supply, a pulse modulator configured to modulate an input signal into a pulse width modulation signal, a switching stage configured to generate an amplified output signal, and an error feedback signal configured to correct errors in the amplified output signal, where the input signal is comprised of at least one of an analog signal and a digital signal. A method of signal amplification comprising generating, by a pulse width modulator, a pulse width modulation signal, combining, by a switching stage, the input signal and the pulse width modulation signal to form an amplified output signal, and generating, by the switching stage, an error feedback signal, where the error feedback signal is configured to correct errors in the amplified output signal, and where the input signal is comprised of at least one of an analog signal and a digital signal.
