Abstract: 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.
