  "textContent": "A readout circuit for a MEMS gyroscope having a seismic mass. The readout circuit includes: an analog amplitude-/phase-locked loop for monitoring the vibrating motion of the seismic mass and for generating a driver signal to excite and maintain a defined vibrating motion of the seismic mass, a selectively activatable sensing front end for providing measured values of the MEMS gyroscope, a selectively activatable phase-locked loop for providing a demodulation clock signal for the sensing front end, and an energy-management unit, which is designed to set a sensing operating mode for the MEMS gyroscope, in which measured values are acquired with the aid of the sensing front end, or to set a standby operating mode for the MEMS gyroscope, in which no measured values are acquired, the energy-management unit activating the sensing front end and the phase-locked loop in the sensing operating mode and deactivates them in the standby operating mode.",
