Formula for inverting amplifier
WebAn inverting op-amp is a type of operational amplifier circuit used to generate an output that is out of phase as compared to its input through 180 degrees which means, if the input signal is positive (+), then the output signal will be opposite. The inverting op-amp is designed through an op-amp with two resistors. WebIf the same op-amp is used in both inverting and non-inverting modes (with same closed loop gain using appropriate resistors), will the closed loop bandwidth of the op-amp in both cases be the same? For example, Now, if I assume unity gain frequency = 10 MHz, is the bandwidth for both 5 MHz? If I am correct, then why is the GBWP of the closed loop …
