The readout electronics can be divided into four different functional parts, namely the sensor readout itself, signal post-processing, references, and power management. © 2008 Institute of Electrical and Electronics Engineers (IEEE).

Before the focus is shifted to the references and further to power management, different ways to realize the sensor readout are briefly discussed.

A 21.2µA ΔΣ-based interface ASIC for a capacitive 3-axis micro-accelerometer.
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.
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.
