Abstract
A device includes a combining circuitry that receives an incoming signal, and one or more delayed signals from a delay circuitry. The combining circuitry combines the incoming signal and the one or more delayed signals to generate a combined signal. The device includes a comparing circuitry that receives the combined signal from the combining circuitry, and compares a pulse width of the combined signal to a threshold pulse width. When the pulse width of the combined signal is greater than or equal to the threshold pulse width, the comparing circuitry provides the combined signal to an amplifier circuit and provides a null signal to the delay circuitry. The amplifier circuit generates a pulse width modulated (PWM) signal based on the combined signal.
