Layout: Minimize the distance between the p+ and n+ diffusions. Two different versions have been tested. The anode should be the floating node and the cathode must be connected to ac ground. Experimental data (Q at 2GHz, 0.5μm CMOS)†: . Electrons as majority carriers lead to higher Q because of their higher mobility.

General hardware design/BGA PCB design/BGA
Much research has been done on decoupling capacitor selection and placement for BGAs. This application report provides the current best practices, and what TI recommends in general for placement and selection of values. In the past, TI (and many other semiconductor companies) recommended 1 capacitor (cap) per power pin.
Layout of Capacitor
Layout of Capacitor Theory In principle, capacitor is nothing but two adjacent conductor plates with certain type of dielectric in-between. The capacitance is calculated based on the following formula: If d and ε are constants and the area is a rectangle, this formula can be modified as: Therefore, to layout a capacitor, we have to figure out

Layout area of S/H circuit is mostly dominated by the MIMCaps used for charge pump, Bootstrapping and load. Fig 1. Layout of S/H circuit. 2. DAC Layout. The major challenge in the DAC is the choice of capacitor array layout as well as their placement. The concept of capacitor array layout is explained in [5].

6 FAQs about [How to reasonably layout reactive capacitors]
How to layout a capacitor?
In principle, capacitor is nothing but two adjacent conductor plates with certain type of dielectric in-between. The capacitance is calculated based on the following formula: Therefore, to layout a capacitor, we have to figure out the geometric parameters of the rectangle based on C and c, then draw it!
How a capacitor with 2/3 drag reactive power should be installed?
According to this rule, in order to come up with the maximum reduction, a capacitor with (2/3) drag reactive power from the beginning of the feeder must be installed in a place where its distance is (2/3) feeder length in comparison to the beginning of the feeder. Result of the above mentioned method is (2/3) rule.
What are the characteristics of a capacitor?
) Parasitic capacitors to ground from each node of the capacitor. ) The density of the capacitor in Farads/area. ) The absolute and relative accuracies of the capacitor. ) The Cmax/Cmin ratio which is the largest value of capacitance to the smallest when the capacitor is used as a variable capacitor (varactor).
What is the objective of capacitor placement in the electric network?
The objective of capacitor placement in the electric network is to minimize the losses and improve voltage profile. The load and capacitor model, objective function, constraints and power loss calculations are described in this section. The loads and capacitors are modeled as impedance. The impedance model of loads and capacitors are given by Eq.
How to determine the maximum reduction of a capacitor?
The most popular result of analytical methods is the (2/3) rule. According to this rule, in order to come up with the maximum reduction, a capacitor with (2/3) drag reactive power from the beginning of the feeder must be installed in a place where its distance is (2/3) feeder length in comparison to the beginning of the feeder.
What is the most useful method of capacitor placement in a power system?
The most useful method of capacitor placement in the power system is the analytical method. This uses the calculus for capacitor placements to calculate the minimum losses and cost savings. This method supposes that the feeder hasn‟t any sub branches. Its cross-section is the same in all parts and has been distributed equally in the feeder .
