An operational amplifier - UK Essays.
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.

Moreover, Oxford citation style is the only referencing guide that uses footnotes at the bottom of the page unlike the in-text citation styles used by Harvard and A.P.A. Apart from that, drawing up an Oxford style citation list can be time-consuming and a tedious job to do.
This article explains how to realize an operational amplifier using discrete components. General purpose BJT transistors, resistors, diode and capacitor are used to build op-amp.
The operational amplifier compares the reference voltage of the zener with the feedback voltage sampled by resistors R1 and R2. The Darlington Pair design is used here and R3 connected to the regulated supply to reduce the ripple voltage. The operational amplifier (op amp) must be supplied by the unregulated input voltage. (Prof. Gift, 2012).
A High Swinging Ultra-Low-Power Two Stage CMOS OP-AMP in 0.18 um Technology with 1.2v supply, is presented. Cascode technique has been used to increase the dc addition. The unity-gain bandwidth is besides enhanced utilizing a gain-stage in the Miller capacitance feedback way. The proposed opamp.
