Abstract
A signal processing circuit for a gyroscope apparatus is disclosed. The signal processing circuit includes a first electrode and a second electrode pairing with the first electrode. The signal processing circuit, being a negative feedback loop circuit, is configured to be connected with the first electrode and the second electrode and comprises a demodulator configured to convert a current from the first electrode into a voltage and demodulate the converted voltage to output a demodulated signal, an analog-to-digital converter configured to convert the demodulated signal from the demodulator into a digital signal, a proportional-integral-derivative controller that is connected to the analog-to-digital converter, a digital-to-analog converter configured to convert an output signal from the proportional-integral-derivative controller to an analog signal, and a modulator configured to be electrically connected with the second electrode and to be electrically connected with the digital-to-analog converter.
