Abstract: The present invention offers an over-sampling digital-to-analog converter with variable sampling frequencies to process input signals of variable sampling frequencies. The over-sampling digital-to-analog converter comprises an expander, which expands said input signals with a fixed rate of M to produce over-sampling signals; a digital low-pass filter, which filters out high-frequency ingredients of over-sampling signals and then outputs data with a first rate; a data buffer, which receives the outputted data by said digital low-pass filter with the first rate and outputs the data with a second rate; a modulator, which reads data in said data buffer with the second rate and modulates the data; a digital-to-analog converter, which converts the modulated data to analog signals; and an analog low-pass filter, which filters out high-frequency ingredients of said analog signals for producing output signals. No matter how the sampling frequency of the input signals is, due to reading rates of the modulator are the same, the over-sampling digital-to-analog converter ensures that noise is mostly distributed in the high-frequency band.

Abstract: A vacuum sensor for sensing vacuum in a sealed enclosure is provided. The sealed enclosure includes active MEMS devices desired to be maintained in vacuum conditions. The vacuum sensor includes a motion beam anchored to an internal surface in the sealed enclosure. A driving electrode is disposed beneath the motion beam and a bias is supplied to cause the motion beam to deflect through electromotive force. A sensing electrode is also provided and detects capacitance between the sensing electrode disposed on the internal surface, and the motion beam. Capacitance changes as the gap between the motion beam and the sensing electrode changes. The amount of deflection is determined by the vacuum level in the sealed enclosure. The vacuum level in the sealed enclosure is thereby sensed by the sensing electrode.
