Abstract: A clock-signal generator circuit, for generating an output clock signal starting from an input clock signal, includes: a monostable stage having a clock input configured to receive the input clock signal, a control input configured to receive a control signal, and an output configured to supply the output clock signal having a duty cycle variable as a function of the control signal; and a feedback loop, operatively coupled to the monostable stage for generating the control signal as a function of a detected value, and of a desired value, of the duty cycle of the output clock signal.

Abstract: A gyroscope includes: a mass, which is movable with respect to a supporting body; a driving loop for keeping the mass in oscillation according to a driving axis; a reading device, which supplying an output signal indicating an angular speed of the body; and a compensation device, for attenuating spurious signal components in quadrature with respect to a velocity of oscillation of the mass. The reading device includes an amplifier, which supplies a transduction signal indicating a position of the mass according to a sensing axis. The compensation device forms a control loop with the amplifier, extracts from the transduction signal an error signal representing quadrature components in the transduction signal, and supplies to the amplifier a compensation signal such as to attenuate the error signal.
