the bottom plates of the other capacitors are connected to the ground bus. The comparator determines the values of the bits, comparing the voltage on the top plate bus with a voltage that is equal to half of the scale. A great number of papers are devoted to the analysis of SAR ADC errors and the methods for reducing them [1–15].

In this work, parallel plate capacitors are numerically simulated by solving weak forms within the framework of the finite element method. Two different domains are studied. We study the infinite parallel plate capacitor problem and verify the implementation by deriving analytical solutions with a single layer and multiple layers between two plates. Furthermore, we …
Elimination of the effect of bottom-plate capacitors in C-2C DAC …
Practically, a metal chamber is used around C 2 instead of a single plate. In fact, the inter-layer vias and the Metal-1 layer can be placed as a surrounding cubic chamber, as it is shown in Fig. 3.Hence, the fringe capacitors between the bottom-plate of C 2 capacitors and the substrate can be reduced significantly. Thus, the effect of fringe capacitors will be ignorable.

The analysis is based on a series resonant architecture, presented in Fig.2. Power is trans-ferred from V S to V D through the two coupling capacitors C. These two capacitors are in series, so the e ective capacitance between transmitter and receiver is C=2. An H-bridge driver converts V S into an AC voltage to enable current ow through the ...

When a dc voltage V is applied across the capacitor, the movable plate is pulled down to the fixed plate. For parallel plate variable capacitors with air gap, neglecting fringe fields, the capacitance obtained with smooth plates is given by C d = ε 0 A d, where A is the overlap area of the plates, d is the gap between the plates.

Parallel Plate Capacitor
The most common capacitor is the parallel-plate capacitor, illustrated in Figure 14.2 this arrangement, the separation d between the parallel conducting plates is usually small compared to the linear dimensions of the plates. Then the electric field is constant and is perpendicular to each plate, except near the edges of the plates where the field "fringes" slightly.

Capacitor Charging and Discharging when connected to the ground
The net charge of any of those internally connected pairs of plates is always zero. That is, when you charge the capacitors, charge doesn''t leave the wire between C and D, it only moves along it, and is held in place by the electric field of the adjacent plates. If a circuit is completed that allows charge to flow from D''s negative plate to A''s positive plate, the charges will move back to the ...
