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 ...

WebAug 16, 2024 · The gain of the overall amplifier doesn’t have to start decreasing at 10 Hz, because the required gain may be much lower than the open-loop gain of the op-amp. For example, if we want to implement a non-inverting amplifier with a gain of 2 V/V, the corner frequency of the closed-loop gain will be much higher than the corner frequency of the ... WebQuestion: The midrange open-loop gain of an op-amp is 120 dB. With negative feedback this gain is reduced to 80 dB. The closed-loop gain is....
