Abstract
A drive-mode oscillator module for use within a micro-electro-mechanical system (MEMS) device is described. The drive-mode oscillator module is arranged to receive a proof-mass measurement signal from a proof-mass of the MEMS device and to output a proof-mass actuation signal to the proof-mass of the MEMS device. The drive-mode oscillator module comprises a first, higher gain accuracy drive-mode component for generating an actuation signal to be output by the drive-mode oscillator module during an active mode of the MEMS device, and a second, lower power consumption drive-mode component for generating an actuation signal to be output by the drive-mode oscillator module during a standby mode of the MEMS device.
