In this paper, we introduce a two-chip implementation of a capacitive sensor interface circuit, intended especially for the accelerometer. There are several advantages to fabricating the circuits separately. First, one can use this circuit technique when there is no access to micromachining technologies, and commercial sensor must be used. Second, it is likely to provide higher yield since the micromachining process is still complicated and failure-prone. Third, one can use more advanced process for the interface circuit and use more transistors, because micromachining usually uses older processes. One can also apply this circuit for multiplexed sensors. Once a two-chip solution is obtained, it will be less challenging to generate a single-chip implementation.

Also, this pap explains info regarding micromachining technology, level, structure, circuit, interface, accelerometer sensor, feedback, frequency, parasitic capacitor, capacitance, chip, shaping, and output.
