New 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 کاملComparator-based switched-capacitor pipelined analog-to-digital converter with comparator preset, and comparator delay compensation
We present a differential comparator-based switched-capacitor (CBSC) pipelined analog-to-digital converter (ADC) with comparator preset, and comparator delay compensation. Compensating for the comparator delay by digitally adjusting the comparator threshold improves the ADC resolution from 2.5-bit to 7.05-bit. The ADC is manufactured in a 90 nm CMOS technology, with a core area of 0.85 mm 9 0.3...
متن کاملSwitched 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 کاملHigh-accuracy Pipelined A/D Converter Based on Zero-crossing Switched Capacitor Circuits
Technology scaling poses challenges in designing analog circuits because of the decrease in intrinsic gain and reduced swing. An alternative to using highgain amplifiers in the implementation of switchedcapacitor circuits has been proposed [1] that replaces the amplifier with a current source and a comparator. The new comparatorbased switchedcapacitor (CBSC) technique has been implemented in tw...
