In this article the principle of the switched capacitor in a series RLC circuit is presented. The classical methods for phase angle control are described, and a novel control method, where the capacitor is placed in the centre of a bidirectional H bridge switches. Using an electronic circuit simulation program, the representative voltage and current curves are obtained. The phase angle at vario...

This chapter presents the design of the track-and-hold and multiplying digital-to-analog converter functional blocks. They are realized by Switched Capacitors (SC) circuits. Typical SC circuit stage consists of sampling capacitors and Metal Oxide Semiconductor (MOS) switches which turn on and off at the clock rate to store the input signal (charge) on the sampling capacitors and subsequently tr...

The paper describes design requirements of a basic stage (called MDAC Multiplying Digital-toAnalog Converter) of a pipelined ADC. There exist error sources such as finite DC gain of opamp, capacitor mismatch, thermal noise, etc., arising when the switched capacitor (SC) technique and CMOS technology are used. These non-idealities are explained and their influences on overall parameters of a pip...

The presented work deals with analysis of non-ideal effect of pipelined analog-to-digital converter (ADC) such as random capacitor mismatch, comparator offset and finite op-amp gain. These factors arise during a conversion in the pipelined ADC when using CMOS technology and switched-capacitors (SC) technique. The pipelined ADC was simulated in MATLAB-Simulink simulation environment. Key-Words: ...

Low-power switched-mode power supply converters are used in applications where size and efficiency are critical. The buck converter size can be reduced by elimination of the bulky filter capacitor. The filtering function of this capacitor can be replaced by an output current ripple compensation circuit. The compensating circuit is applied, based on inductor current measurement and linear amplif...

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 switched capacitor circuits has been proposed [1] that replaces the amplifier with a current source and a comparator. The new comparator-based switch capacitor (CBSC) and zero-crossing-based circuit (ZC...

The increase of transmission frequency reveals more merits than lowor medium-frequency distribution among different kinds of power applications. Highfrequency inverter serves as source side in highfrequency ac (HFAC) power distribution system (PDS). However, it is complicated to obtain a highfrequency inverter with both simple circuit topology and straightforward modulation strategy. A novel sw...

Various basic, efficient and cheap techniques are used for the purpose of life forecast and failure detection of aluminum electrolytic capacitors which are utilized as a part of many power electronic converters. The main idea of these techniques is to calculate the values of Equivalent Series Resistance (ESR) and Capacitance (C). Observing the ESR values, valuation of changes in voltage and cur...
