Abstract
An embodiment includes a forward data receiving device that demodulates and receives an Amplitude Shift Keying (ASK) modulation signal, and includes: an input module configured to receive the ASK modulation signal as an input; a resonance regulating rectifier module configured to regulate and rectify an input voltage of the ASK modulation signal on the basis of Pulse Width Modulation (PWM) according to a preset target voltage, and apply a regulated voltage through an output transistor; and a demodulation module configured to demodulate the ASK modulation signal according to a trend in a change of the input voltage compared to the regulated voltage, wherein the resonance regulating rectifier module includes a comparison unit configured to generate a gate signal for controlling on/off of the output transistor, and generate a sample signal for demodulating the ASK modulation signal.
