Abstract

A demodulator for processing a PWM (pulse width modulation) signal includes a variable capacitor, a charging unit, a discharging unit, and a tuner. The charging and discharging units charge or discharge the variable capacitor depending on the PWM signal. The tuner determines a capacitance of the variable capacitor and a discharge current of the discharging unit for proper operation of the demodulator in various RF environments.
