Control circuit of a MEMS gyroscope, MEMS gyroscope and control method

A control circuit for a MEMS gyroscope, configured to receive a measurement signal having a quadrature component and a sensing component from the MEMS gyroscope, the control circuit comprising:

• an input stage configured to acquire an input signal and to generate an acquisition signal in response to the input signal, the input signal being a function of the measurement signal and of a quadrature cancellation signal;
• a processing stage configured to obtain a first component of the acquisition signal, the first component of the acquisition signal being indicative of the sensing component of the measurement signal and having a sensing frequency band;
• and
• a quadrature correction stage configured to extract a second component of the acquisition signal and to generate the quadrature cancellation signal based on a reference signal, the second component of the acquisition signal being indicative of the quadrature component of the measurement signal,
• wherein the quadrature cancellation signal is a signal modulated as a function of the second component of the acquisition signal, at an update frequency which is outside the sensing frequency band.
