This paper presents to find a sufficient model of integrated passive structures for high frequency analysis and prediction in power electronic circuits. At high frequencies there are many parasitic oscillations that begin to circulate in the power circuits. Some sources of these oscillations include inter-component connections and their environment begin having electromagnetic significance, unmodeled characteristics in the semiconductor devices, Parasitic impedance characteristics of discrete passive components, Interference from an imperfect source and a ground plane and Interference from radiation. A simulation model involving most of these factors can prove valuable in distinguishing between the causes of parasitic oscillations. A designer can modify the parameters of a particular parasitic element, and observe its effect on the oscillations, hence seeing which factors are the most significant.

Parasitic integration for a single supply differential capacitive sensing technique is presented in this paper. In real capacitive sensor measurement, parasitic impedance exists in its measurement. This paper objective is to study the effect of capacitive and resistive parasitic to the capacitive sensor circuit. The differential capacitive sensor circuit derivation theory is elaborated first. Then, comparison is made using simulation. Test was carried out using frequency from 40 kHz up to 400 kHz. Result is presented and have shown good linearity of 0.99984 at 300 kHz, R-squared value. This capacitive sensor is expected to be used for energy harvesting application.
