摘要： A BASK demodulator includes a signal modifying circuit and a low pass filter (LPF) that couples an amplifier to an output of the modifying circuit. The modifying circuit includes a signal scaling circuit, a rectifying circuit and an AC coupling circuit. A signal shaping circuit couples an output of the amplifier to an output of the demodulator. The signal scaling circuit scales an input BASK modulated signal to provide an unclipped scaled and biased alternating signal that alternates about a bias voltage at a minimum carrier frequency. The rectifying circuit rectifies the unclipped signal to provide a partially rectified signal that is decoupled by the AC coupling circuit to provide a clipped scaled and biased alternating signal. The LPF removes the signal from the clipped scaled and biased alternating signal to provide a demodulated signal, which then is amplified by the amplifier and shaped by the shaping circuit.
