Evaluate the “operational amplifier” as a device. Your task is to write a report (400 words) that discusses the properties of an ideal operational amplifier. Please include diagrams to aid your discussion. Describe the operation of the following operational amplifiers: a) Non-Inverting Amplifier. b) Summing Amplifier. c) Differential Amplifier.
AC Operational Amplifiers Agrim Ganti University College London 5th December 2008 ABSTRACT The report is written on an investigation which comprises of testing three operational amplifier circuits with AC signals. The three types of circuit include the integrator, the AC inverting amplifier and the AC non-inverting amplifier circuit.
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. In this configuration, an op-amp produces an output potential (relative to circuit ground) that is typically hundreds of thousands of times larger than the potential difference between its input terminals.
Operational amplifiers can be used in construction of active filters, providing high-pass, low-pass, band-pass, band-reject and delay functions. The high input impedance and gain of an op-amp allow straightforward calculation of element values, allows accurate implementation of any desired filter topology with little concern for the loading effects of stages in the filter or of subsequent stages.
Operational Amplifiers Lab Abstract: This lab will demonstrate the different forms of the operational amplifier. By connecting circuits from previous labs to an operational amplifier, we will be able to see the different operations that a Op-amp can perform.
The bandwidth of an ideal operational amplifier is infinite and can amplify any frequency signal from DC to the highest AC frequencies. However, typical bandwidth is limited by the Gain-Bandwidth product. GB product is equal to the frequency where the amplifiers gain becomes unity.
Operational amplifiers were invented a long time ago and they ere also used in computers of old age. In those computers the function of operational amplifiers was to perform mathematical operations. Operational amplifiers have a large no of applications and are most commonly use to perform some electronic operations like signal conditioning.
Operational amplifiers used as amplifiers (they have other uses too) are usually operated in negative feedback circuits, which set the gain, bandwidth and other features to required, well-defined, values.
