Conventional switched capacitor converters have an inherent drawback that their efficiency decreases as the output current increases. This inherent drawback is due to a periodical forced charging and discharging operation in the internal switched capacitors accompanied by a large capacitor current. Their efficiency can not be increased by decreasing its internal resistance. As a result, convent...

VAR support should be supplied as close to the load as possible to minimize transmission losses. For voltage control and for improvement of total power factor in a distribution system the circuit- breaker switched capacitor banks can be used. The problems with this solution are the voltage steps caused by the large sizes of the capacitor banks as well as the transients caused on insertion. Thyr...

Design of switched capacitor circuits in scaled CMOS technologies is becoming difficult because of low device intrinsic gain and reduced power supply voltage. To solve these problems, comparator-based switched-capacitor (CBSC) circuits and zero-crossing based circuits (ZCBC) were suggested as a possible solution to the op-amp based circuits. In this thesis, we explore zero-crossing based circui...

A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...

A simple but highly accurate method is proposed to find the dc parameters of active or passive switchedcapacitor (SC) circuits. It is based on the dc model of a general SC branch.

This paper presents a predictable fixed gain instrumentation amplifier using switched capacitor instead of resistor to improve the accuracy of the gain as 10. This instrumentation amplifier builds up by two operational amplifiers which connect by switched capacitor. These switched capacitors are used to stable the whole circuit, fix the gain of total instrumentation amplifier. Using two operati...
