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.

摘要： Embodiments described herein include a quadrature phase corrector (QPC) which includes multiple differential amplifies for correcting the phase of one or more clock signals. In one embodiment, the differential amplifiers are arranged in an input stage, cross-coupled stage, and ring stage. The input stage receives and buffers the input clock signal (or signals). The cross-coupled stage includes one or more latches that force one clock signal high and another low which causes the QPC to oscillate. The ring stage outputs four clock signals with adjusted phases relative to the input clock signals. In one example, the ring stage outputs a quadrature clock signal that includes four clock signals phase shifted by 90 degrees.
