Download or read book Basics of Capacitor written by Prasun Barua and published by Prasun Barua. This book was released on with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Welcome to Basics of Capacitor! This is a nonfiction science book which contains various topics on basics of Capacitor. A capacitor is a two-terminal electrical device which uses an electric charge to store energy. It is made up of two electrical conductors separated by a distance. The space between the conductors can be filled with a vacuum or a dielectric, which is an insulating material. Capacitance refers to the capacitor's ability to store charges. Capacitors store energy by keeping opposing charges apart. A parallel plate capacitor is the most basic type of capacitor, consisting of two metal plates with a gap between them. Capacitors come in a wide variety of shapes, sizes, lengths, girths, and materials. The ratio of a system's change in electric charge to the corresponding change in its electric potential is known as capacitance. The capacitance of any capacitor can be either fixed or variable, depending on its usage. Apart from charge and voltage, capacitance also depends on the shape and size of the capacitor and also on the insulator used between the conducting plates. Capacitors are used for storing energy, power conditioning and signal processing. This is the first edition of the book. Thanks for reading the book.

This book was released on 2012-12-06 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to present analysis and design principles, procedures and techniques of analog integrated circuits which are to be implemented in MOS (metal oxide semiconductor) technology. MOS technology is becoming dominant in the realization of digital systems, and its use for analog circuits opens new pos sibilities for the design of complex mixed analog/digital VLSI (very large scale in tegration) chips. Although we are focusing attention in this book principally on circuits and systems which can be implemented in CMOS technology, many con siderations and structures are of a general nature and can be adapted to other promising and emerging technologies, namely GaAs (Gallium Arsenide) and BI MOS (bipolar MOS, i. e. circuits which combine both bipolar and CMOS devices) technology. Moreover, some of the structures and circuits described in this book can also be useful without integration. In this book we describe two large classes of analog integrated circuits: • switched capacitor (SC) networks, • continuous-time CMOS (unswitched) circuits. SC networks are sampled-data systems in which electric charges are transferred from one point to another at regular discrete intervals of time and thus the signal samples are stored and processed. Other circuits belonging to this class of sampled-data systems are charge transfer devices (CTD) and charge coupled dev ices (CCD). In contrast to SC circuits, continuous-time CMOS circuits operate continuously in time. They can be considered as subcircuits or building blocks (e. g.

Download or read book Switched capacitor DACs Using Open Loop Output Drivers and Digital Predistortion written by Clayton Hollis Daigle and published by Stanford University. This book was released on 2010 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-speed communication systems, such as the 10 Gb/s Ethernet standard for copper cabling (10GBASE-T), use digital signal processing (DSP) to overcome the noise and bandwidth constraints of communication channels and, thereby, improve network throughput. The sophistication of these DSP techniques is possible because engineers can implement them using very little area and power in modern CMOS processes. And as CMOS technology scales, the power and area costs of digital logic become even more favorable. The requirements of communication systems also put pressure on circuit designers to develop higher-fidelity, higher-speed digital-to-analog converters (DACs). Unfortunately in this case, CMOS technology scaling offers a mixed bag of trends: some favorable to the most prevalent techniques used in DAC design and others unfavorable. The research presented in this dissertation is an attempt to let CMOS scaling trends guide the DAC design process. To this end, we have developed a new DAC architecture that relies on DSP to overcome some of the limitations encountered in analog and mixed signal design. The architecture consists of a digital predistortion block, a switched-capacitor DAC core, an open-loop output driver, a calibration ADC and a calibration algorithm. During normal operation, the predistortion block operates on the input data stream in such a way that nonlinearties in the DAC core and open-loop output driver are cancelled. Because these nonlinearities can change over time, the calibration ADC monitors the DAC output in the background, allowing the calibration algorithm to continuously update the predistortion coefficients. The predistortion block is implemented as a lookup table that re-maps each input sample to a unique internal value. This allows the predistorter to consume low power, but it also limits the kinds of errors that can be cancelled. Only memoryless nonlinearities, which are nonlinearities that are not a function of signal frequency, can be corrected. Existing DAC architectures are not good candidates for this kind of correction because their performance varies significantly across frequency. Therefore, the architecture that we have developed was designed so that its dominant nonlinearity mechanisms are approximately memoryless relative to the frequencies of interest. A 12-bit, 800-MS/s prototype chip demonstrating the new architecture was fabricated in a 90-nm CMOS process. The prototype achieves better than 58 dB SFDR for signal frequencies below 200 MHz and better than 53 dB SFDR for signal frequencies below 400 MHz. The full-scale output current is 16 mA, but by changing the resistive load seen by the DAC, we tested output voltage swings from 0.65 Vppd to 2.9 Vppd. We could discern no difference in SFDR performance for large or small output voltage swings.
