WebAn example of PWM in an idealized inductor driven by a voltage source modulated as a series of pulses, resulting in a sine-like current in the inductor. The rectangular voltage pulses nonetheless result in a more and more smooth current waveform, as the switching frequencyincreases. The current waveform is the integral of the voltage waveform. WebApplications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems. This analog switch is operational at 0.8-V to 2.7-V V CC, but is designed specifically for 1.1-V to 2.7-V V CC operation.
