Opamp – Operational Amplifier
What is an Opamp ? Opamp is the abbreviation of Operational Amplifier. An operational amplifier is a direct coupled high gain amplifier usually consisting of one or more differential amplifiers followed by a level transistor and an output stage. The output stage is generally push-pull or complementary symmetry push-pull amplifier. Opamps are building blocks of analog circuitry and is also known as differential amplifier as its output depends on difference between input signals. It can also be used to amplify both DC as well...
