How do you calculate the open-loop gain?
How do you calculate the open-loop gain? Voltage gain can also be expressed in dB terms, as gain in dB = 20 × logAVOL. Thus, an open-loop gain of 1V/µV is equivalent to 120 dB. Current feedback (CFB) op amps have a current input and a voltage output, so their open-loop transimpedance gain is expressed in volts per ampere or ohms (kΩ or MΩ). What is open-loop gain in op amp? Op-amps have a high gain (around 105, or 100 dB). The gain of an op-amp without feedback is called the open-loop gain whereas the gain of an op-amp with...
