Application of Thau Observer for Fault Detection of Micro Parallel Plate Capacitor Subjected to Nonlinear Electrostatic Force

This paper investigates the fault detection of a micro parallel plate capacitor subjected to nonlinear electrostatic force. For this end Thau observer, which has good ability in fault detection of nonlinear system has been presented and governing nonlinear dynamic equation of the capacitor has been presented. Upper and lower threshold for fault detection have been obtained. The robustness of th...

Mismatch-Shaped Pseudo-Passive Two-Capacitor DAC

A simple mismatch-shaping scheme is proposed for a two-capacitor DAC. Unlike in other mismatchshaping systems, the shaped error is generated by direct ltering of a well-de ned bounded signal, which can be generated as white noise. The operation is closely related to a speci c digital interpolation lter, but arbitrary properties of the overall interpolation characteristic can be assured. Simulat...

Two-Dimensional Inductor-Capacitor Lattice Synthesis

We consider a general class of two-dimensional passive propagation media, represented as a planar graph where nodes are capacitors connected to a common ground and edges are inductors. Capacitances and inductances are fixed in time but vary in space. Kirchhoff’s laws give the time dynamics of voltage and current in the system. By harmonically forcing input nodes and collecting the resulting ste...

Simulation and experimental modeling of a multipoles variable capacitor for an electrostatic wind energy harvester

The aim of this work is to study the effect of rotational motion generated by wind on the capacitance variation of the multipole variable capacitor. AutoCAD software was used to model the variable capacitor and to calculate the capacitance variation relative to the angular position caused by wind. Subsequently, experiments were carried out to measure the capacitance variation relative to the an...
