Op-amp multivibrator is an electronic circuit that generates non-sinusoidal waveforms such as square or triangular signals.
The operational amplifier or OP-AMP is a direct coupled, high gain amplifier used to perform a wide variety of mathematical operation
Transistor’s within the OP-AMP must be biased so that have the current values of base and collector current and collector to emitter voltages.
The operational amplifier is direct-coupled high gain differential amplifier. The term operational amplifier was originally used for the D.C
The operational amplifier is an amplifier which is directly coupled between the output and input, having a very high gain.
