A pulse width modulation system comprises an analog component and a digital component. The analog component operates to separate a local oscillator signal with different phase shifts and introduce an offset (i.e., a time delay) to analog signals being receive at an input with a tuning operation that fine tunes in the analog signals in the analog (continuous time) domain. The analog component comprises a plurality of analog delay lines that respectively process carrier signals having a different phase shifts. Digital delay lines convert the analog signals to digital square waves with the same time delay and at the same resolution as the analog output signal.

Mixed analog-digital pulse-width modulator

A pulse width modulation (PWM) system comprises an analog component and a digital component. The analog component introduces an offset (i.e., a time delay) to analog signals being received at an input with a tuning operation that fine tunes in the analog signals in the analog (continuous time) domain. The analog component comprises an analog delay line comprising a plurality of analog delay components configured to introduce the time delay to the analog signals based on a model of a transmission line.
