Of the circuits, the first two are subject to most thorough investigation with the capacitance ratio to frequency ratio converter being of particular interest.

This circuit is based upon a switched capacitor, frequency controlled, negative feedback loop which permits implementation with modest quality analogue components, such as are provided with a standardcell ASIC CMOS process.

This implementation exhibits greatly reduced chargefeedthrough, and circuit behaviour is in accordance with a modification to the firstorder analysis that includes the effects of chargefeedthrough.

Importantly, no frequency locking and much reduced jitter is observed.

The research described in this thesis concentrates on the design of low-power sensor interfaces for capacitive 3-axis micro-accelerometers.

The primary goal throughout the thesis is to optimize power dissipation. Both current and voltage references are required in most analog and mixed-signal systems.

The first interface circuit is the realization of a current-mode approach that has the main advantage of being able to produce a fully-differential output also from a single-ended sensor by using just a fixed reference capacitor.The circuit, prototyped in a commercial 0.8-µm CMOS process, was estimated capable of achieving an accuracy of around 0.2% relative to full-scale which may be sufficient in many applications.This thesis reports an investigation into integrated interface circuits for switched capacitor sensors for application in industrial process control instrumentation networks.Three circuits are presented: an absolute capacitance to voltage converter; a capacitance ratio to frequency ratio converter; and a capacitance ratio to voltage ratio converter.Such oscillators suffer from poor jitter and phase noise performance, the quantities of which also deserve discussion in this thesis. © 2006 Institute of Electrical and Electronics Engineers (IEEE).
