چکیده

In this paper we discuss layout generation of on-chip matched capacitors with accurate capacitance ratios. Capacitor sizing and placement suitable for design of error insensitive capacitance ratios are discussed including a proposed algoritm for common-centriod placement. Also, a regular layout structure is proposed that is suitable for implementation of capacitors with well matched capacitance ratios.

Optimal Placement and Sizing of DGs and Shunt Capacitor Banks Simultaneously in Distribution Networks using Particle Swarm Optimization Algorithm Based on Adaptive Learning Strategy

Abstract: Optimization of DG and capacitors is a nonlinear objective optimization problem with equal and unequal constraints, and the efficiency of meta-heuristic methods for solving optimization problems has been proven to any degree of complex it. As the population grows and then electricity consumption increases, the need for generation increases, which further reduces voltage, increases los...

How to Choose & Place Decoupling Capacitors to Reduce the Cost of the Electronic Products

PCB designs, it becomes more challenging to manage clean power supplies. The number of decoupling capacitors used for a power delivery system keeps increasing as well. This causes two problems for board designers and layout engineers: 1) How to determine the numbers and the types of decoupling capacitors needed for a particular design; and 2) Where to place the selected capacitors on board. Wit...

ESR and ESL of Ceramic Capacitor Applied to Decoupling Applications

Power distribution system noise affects computer product timing performance, signal integrity and electromagnetic interference. Between 1 MHz and 1 GHz, the primary means of reducing power distribution noise is with ceramic decoupling capacitors. To achieve a certain target impedance, it is important to characterize the ESR of ceramic decoupling capacitors as they directly determine the number ...

Efficient polygon enclosure algorithms for device extraction from VLSI layouts

The typical description of a VLSI layout is the geometrical description of masks. Layout verification [4] is the testing of a layout to see if it satisfies design and layout rules. An important problem in layout verification is layout device extraction, which involves detection of capacitors, resistors, transistors etc. from the geometrical description of masks. The layout extraction process st...
