Switched Capacitor Filter
A Switched Capacitor circuit is an electronic circuit element used for discrete time signal processing. It works by moving charges into and out of capacitors when switches are opened and closed. Usually, nonoverlapping signals are used to control the switches, so that not all switches are closed simultaneously. Filters implemented with these elements are termed switched capacitor filters. Unlik...
متن کاملCapacitor Mismatch Compensation for the Quasi-Passive Switched-Capacitor DAC
A method to eliminate the effect of capacitor mismatch for a switched-capacitor DAC is described. The method consists of two elements. The first element is the use of a compensating switching algorithm, which can eliminate the effect of capacitor mismatch only for some digital input values. The second element is that each digital word is written as the sum of two other words for which the capac...
متن کاملA Capacitor Paradox
Two capacitors of equal capacitance C are connected in parallel by wires of negligible resistance and a switch, as shown in the lefthand figure below. Initially the switch is open, one capacitor is charged to voltage V0, and charge Q0 = CV0, while the other is uncharged. At time t = 0 the switch is closed. If there were no damping (dissipative) mechanism, the circuit would then oscillate foreve...
متن کاملCompanding Switched Capacitor Filters
In this paper, two possible switched capacitor implementations of companding lters are discussed. The governing di erence equations, an estimate of the increase in the dynamic range for a given power consumption and possible topologies are given.
متن کاملFuseless Capacitor Bank Protection
The use of fuseless capacitor banks requires subtle changes in the protection approach from the more traditional fused banks. This paper covers the aspects of protecting fuseless capacitor banks of various voltage classes. Comparison of fused versus fuseless capacitor bank protection is discussed, along with examples and insights from Minnesota Power’s experiences with fuseless capacitor banks.
