In this paper, we present about the study of operational amplifier test procedure and methods. Operational Amplifiers (Op-amps) are one of the most widely used building blocks for analog and mixed-signal systems. They are employed from dc bias applications to high-speed amplifiers and filters. General purpose op-amps can be used as buffers, summers, integrators, differentiators, comparators, negative impedance converters, and many other applications. The two-pole model widely used in the test analysis to assess the parameters of an op amp is not accurate and may be unsuitable for gain boosting op amp designs. A more complex model with more than two poles may require tedious analysis and a large amount of calculation. Most reported op amp measurement methods require a complicated test circuit, delicate calibration, and sophisticated test instrumentation. The practical bench test of the open loop gain along with other op amp characteristics are addressed alsoin this paper.
