A design for an amplifier for bioelectric events is presented that has fewer parts than conventional designs. The design allows the construction of amplifiers of a high quality in terms of noise and common mode rejection, with reduced dimensions and with a lower power consumption. Gain, bandwidth and number of channels are easily adapted to a wide range of biomedical applications.

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.

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. An operationalamplifier is a multistage amplifier and consists of adifferential amplifier stage, a high-gain CE amplifierstage and class B push-pull emitter follower. Because of their multi-purpose use, OP-Amps are. Operational Amplifiers used in all branches of electronics, both digital and linear circuits.

Operational Amplifiers; Design and Applications

Embed Size px x x x x Abstract - This paper presents a multimedia tutorial tolearn operational amplifier fundamentals. This tutorial isaimed at the practicing engineer who needs to recall thetheory for a quick op-amp circuit design and at the studentwhich has never studied op-amps and needs a quickintroduction to the topic. The tutorial is multimediadisplaying pictures and circuit diagrams including oralexplanations to speed up the learning procedure. Thistutorial package is written in Visual Basic 3.

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.

Она ощутила запах Хейла, но повернулась слишком поздно. И тут же забилась, задыхаясь от удушья. Ее снова сжали уже знакомые ей стальные руки, а ее голова была намертво прижата к груди Хейла. - Боль внизу нестерпима, - прошипел он ей на ухо. Колени у Сьюзан подкосились, и она увидела над головой кружащиеся звезды. ГЛАВА 80 Хейл, крепко сжимая шею Сьюзан, крикнул в темноту: - Коммандер, твоя подружка у меня в руках.

Я хочу открыть этот проклятый файл и ознакомиться с созданной Танкадо программой. Сьюзан была столь же любопытна, как и ее шеф, но чутье подсказывало ей, что расшифровка алгоритма Цифровой крепости неразумна, какой бы интерес это ни представляло. В данный момент эта чертова программа надежно зашифрована и абсолютно безопасна. Но как только шифр будет взломан… - Коммандер, а не лучше ли будет… - Мне нужен ключ! - отрезал. Сьюзан должна была признать, что, услышав о Цифровой крепости, она как ученый испытала определенный интерес, желание установить, как Танкадо удалось создать такую программу.

 Нет, коммандер! - вскрикнула Сьюзан.  - Нет. Хейл сжал ее горло. - Если вы вызовете службу безопасности, она умрет. Стратмор вытащил из-под ремня мобильник и набрал номер. - Ты блефуешь, Грег.

Сьюзан наклонилась к Дэвиду и шепнула ему на ухо: - Доктор. Он смотрел на нее с недоумением. - Доктор, - повторила.  - Скажи первое, что придет в голову.

 Грег, - сказала она, и голос ее зазвучал мягче, хотя далось ей это нелегко.  - Сегодня я не в духе. Меня огорчают твои разговоры о нашем агентстве как каком-то соглядатае, оснащенном современной техникой.

 Неужели. - Да. После того как я вскрыл алгоритм Попрыгунчика, он написал мне, что мы с ним братья по борьбе за неприкосновенность частной переписки. Сьюзан не могла поверить своим ушам. Хейл лично знаком с Танкадо.
