1. A reading circuit of a gyroscope, comprising:

  • a driving unit, generating a resonance signal for a resonator of the gyroscope, and generating a demodulation signal;

    a high pass filter, having an input terminal for receiving an output signal of a Coriolis accelerometer of the gyroscope;

    a signal processing unit, coupled to the driving unit and the high pass filter, providing a modulation signal to the Coriolis accelerometer, and processing and demodulating an output of the high pass filter according to the demodulation signal to output a demodulation result; and

    a low pass filter, coupled to the signal processing unit and receiving the demodulation result.
