Abstract
A digital demodulator includes a resonator having a resonance frequency same as a carrier frequency to store a charge corresponding to a digital signal modulated by phase shift keying, a capacitor to store the charge of the resonator, an amplifier including an input node and an output node between which the capacitor is connected to convert a stored charge of the capacitor into a voltage signal, and a controller configured to accumulate in the resonator the charge induced by the frequency signal modulated by phase shift keying in a first control mode and configured to transfer the charge of the resonator to the capacitor in a second control mode, to output the voltage signal corresponding to the stored charge of the capacitor from the output node of the amplifier.
