dc.description.abstract	This thesis consists of six publications and an overview of the research topic. The overview concentrates on background information of the capacitive accelerometers and front-ends. The publications focus on two low-power front-ends that were implemented for capacitive three-axis accelerometers and their operation as a part of an interface. The switched-capacitor front-ends that were implemented are based on the charge-balancing structures, namely a self-balancing bridge and a ΔΣ front-end, which convert the capacitive acceleration information to analog and digital signals, respectively. Both structures operate mechanically in open-loop configuration and are capable of reducing the effects of the electrostatic forces and displacement-to-capacitance conversion. According to the performance comparison presented in this thesis, both interfaces, which were implemented around the front-ends, exhibit competitive performance when compared to the commercial products of the day.	en
