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 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 کاملLow-voltage Switched-capacitor Resonators
The recent explosion of interest in wireless personal communication systems motivates the development of fully integrated radio receivers. The parallel reduction of the feature sizes in CMOS technology, and hence higher levels of integration. enable the combined integration of a bandpass or baseband analog-to-digital converter with the traditional front-end receiver building blocks. While ths t...
متن کاملNew Switched-Capacitor Pipelined ADC
The paper deals with a new 12-bit low power switched-capacitor (SC) ADC for portable applications, such PDA, notebook etc. The paper describes design of ADC and its behavioural modelling regarding low power consumption. The Op-Amp sharing technique and capacitor scaling approach are utilized to obtain it. The basic block topology design is outlined too. The cancellation techniques to avoid the ...
متن کاملLow-voltage switched-capacitor circuits
One of the key limitations of state-of-the-art fine linewidth CMOS technologies is the restricted power-supply voltage, limited by the low junction-breakdown voltage of the process and by the thin gate oxide, prone to voltage stress and breakdown. Also, in some applications, the available external power source may limit the supply voltage; for example, this source may be a 1.2 V battery, with a...
