Design with Operational Amplifiers and Analog Integrated Circuits - Sergio Franco

An operational amplifier often op amp or opamp is a DC-coupled high- gain electronic voltage amplifier with a differential input and, usually, a single-ended output. Operational amplifiers had their origins in analog computers , where they were used to perform mathematical operations in linear, non-linear, and frequency-dependent circuits. The popularity of the op amp as a building block in analog circuits is due to its versatility. By using negative feedback , the characteristics of an op-amp circuit, its gain, input and output impedance , bandwidth etc. Op amps are used widely in electronic devices today, including a vast array of consumer, industrial, and scientific devices. The op amp is one type of differential amplifier.

Embed Size px x x x x Historically, an operational amplifier OP-Amp was designed to perform suchmathematical operations as addition,subtraction, integration and differentiation. Hence,the name operational amplifier.

A method by means of which the dynamic range of signals may be increased and the dynamic error of the input stages of measuring devices based on Rail-to-Rail operational amplifiers reduced is described. The electrical circuit of the equipment is developed. Results of testing of Rail-to-Rail operational amplifiers in tracking power supply are presented.

Published June by Mcgraw-Hill Tx. Written in English. The heart of the analog computer was a device called an operational amplifier because it could be configured to perform many mathematical operations such as multiplication, addition, subtraction, division, integration, and differentiation on the input signals. The name was shortened to the familiar op amp, as we have come to know and love them. This book provides a Operational Amplifiers; Design and Applications book foundation in opamps. I would definitely recommend it, plus, for the price, it is a steal. Eventhough this is a great text, in my opinion it is replaced by the more modern and complete Design With Operational Amplifiers And Analog Integrated Circuits McGraw-Hill Series in Electrical and Computer Engineering Cited by: This proven textbook guides readers to a thorough understanding of the theory and design of operational amplifiers OpAmps.

This invention relates generally to operational amplifier op amp circuits and, more particularly, to op amp circuits having means for reducing the generation of noise. In the past, op amp circuits have typically included a first amplification stage having a differential pair of matched transistors in a common-emitter configuration. The base elements of the two transistors serve, respectively, as non-inverting and inverting input terminals, and an output signal, proportional to the difference between signals being applied to the two input terminals, is produced at the collector element of one of the transistors. To ensure stability, the gain-bandwidth product of the first amplification stage must ordinarily be limited so that propagation delays in second and subsequent amplification stages won't reduce the phase margin by too much at the unity-gain frequency of the first stage. The customary technique for limiting the gain-bandwidth product of the first amplification stage is to place a resistor in the emitter circuit of each of the two transistors. Unfortunately, these resistors have an adverse effect on the noise power generated in the first stage, since noise power density is directly proportional to the emitter resistance.
