PWM Modulator Using Op-Amp

This is a simple PWM modulator circuit. Comparing the message signal to a ramp or triangular waveform is the simplest way to produce a PWM signal. When the input is greater than the triangular waveform (the carrier), the resulting output is high, when the input is less than triangular waveform, the output is low. So, […]
