ABSTRACT:
An improved clocked data converter with a vibrating microelectromechanical systems (MEMS) resonator. The MEMS resonator is used as part of the clock circuitry of an analog to digital converter or a digital to analog converter. The MEMS resonator may be used as the frequency determining element of an on-chip oscillator, or as a bandpass filter used to clean up an external clock signal.
