The midrange open-loop gain of an op-amp

WebA certain op-amp has three internal amplifier stages with midrange gains of 30 dB, 40 dB, and 20 dB. Each stage also has a critical frequency associated with it as follows: fc1 = 600 Hz, fc2 = 50 kHz, and fc3 = 200 kHz. (a) What is the midrange open-loop gain of the op-amp, expressed in dB? WebOperational Amplifier General Conditions. • The Operational Amplifier, or Op-amp as it is most commonly called, can be an ideal amplifier with infinite Gain and Bandwidth when used in the Open-loop mode with typical DC gains of well over 100,000 or 100dB. • The basic Op-amp construction is of a 3-terminal device, with 2-inputs and 1-output ...

WebNov 20, 2024 · The formula you quote is not the gain of an opamp. It is the gain of a circuit containing an opamp and several resistors. That formula only holds when the open loop gain of the opamp is much larger than that given by the formula. When that is the case, the actual value of the opamp open loop gain drops out of the equation.

WebOp-amps have a high gain (around 105, or 100 dB). To achieve stable operation, op-amps are used with negative feedback. The gain of an op-amp without feedback is called the open-loop gain whereas the gain of an op-amp with a feedback circuit is called the closed-loop gain.
