A reading circuit of a gyroscope is provided. The reading circuit includes a driving unit, a high pass filter, a signal processing unit, and a low pass filter. The driving unit generates a resonance signal for a resonator of the gyroscope and generates a demodulation signal for the signal processing unit. The signal processing unit provides a modulation signal to a Coriolis accelerometer of the gyroscope. An input terminal of the high pass filter receives an output signal of the Coriolis accelerometer. The signal processing unit processes and demodulates an output of the high pass filter according to the demodulation signal and outputs a demodulation result to the low pass filter.
