Operational Amplifier and Oscillators: Virtual ground concept, output offset voltage and CMRR of op-amp and Positive feedback and Barkhausen criteria for oscillations

What is an Op-Amp ? Low cost integrating circuit consisting of: Transistors Resistors Capacitors Able to amplify a signal due to an external power supply Name derives from its use to perform operations on a signal. Applications of Op-Amps Adder Subtraction Comparators Multiplication/ Division Integrators Differentiators Analog to Digital Converters Pin configuration of op amp … Read more
