In this configuration, an op amp produces an output potential It has high common mode rejection ratio. One of the important feature of differential amplifier is that it tends to reject or nullify the part of input signals which is common to both inputs. Amplifiers Electronics. Basics Of Operational Amplifier Operational Amplifier, also called as an Op-Amp, is an integrated circuit, which can be used to perform various linear, non-linear, and mathematical operations. Best resources for eee, ece students. That is, all the stray capacitances are ignored. The reference current source is created using the current mirror 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. Example analysis of the inverting, noninverting, and differential-amplifier circuits shows how calculations are performed. In today’s tutorial, we will have a look at Introduction to Differential Amplifier.It is a type of amplifier which amplify the difference of two input signal. As the name indicates Differential Amplifier is a dc-coupled amplifier that amplifies the difference between two input signals. Its function is to amplify the differential voltage between the + input terminal (non -inverting terminal) and the - input terminal (inverting terminal). The differential amplifier is one of the important circuits in analog systems and circuit designs. Some op-amps are even specifically designed to be used as such and don’t require external circuitry.
