Digital Distortion-Free PWM and Click Modulation
IEEE Transactions on Circuits and Systems II: Express Briefs, 2018 This brief exhibits the relationship between the analog click modulator, which produces a binary pulse width modulation (PWM) signal with separated baseband, and recently reported fully digital, baseband distortion-free PWM algorithms (BBDFPWM). We show that BBDFPWM not only is a discrete-time version of the click modulator but also can operate in real-
