  • METHOD AND APPARATUS FOR GENERATING A PROOF-MASS DRIVE SIGNAL
    Publication number: 20150280949
    Abstract: A drive-mode oscillator module generates at least one proof-mass drive signal for use within a micro-electro-mechanical system (MEMS) device. The drive-mode oscillator module comprises at least one gain control component arranged to receive at least one proof-mass motion measurement signal, and to generate a digital modulation control signal based at least partly on the at least one proof-mass motion measurement signal, and at least one modulation component arranged to receive the digital amplitude modulation control signal, and to output at least one proof-mass drive signal. The at least one modulation component is arranged to digitally modulate the at least one proof-mass drive signal based at least partly on the received digital amplitude modulation control signal.
