Because of a manufacturing error, the open-loop gain of each op-amp in the circuit is only . The open-loop input and output resistances are and , respectively. Determine the closed-loop parameters: (a) , (b) , and (c) . (d) What is the ratio of the actual closed-loop gain to the ideal value?
An amplifier with manufacturing error is given. We need to determine, (a) input resistance (b) output resistance (c) closed loop gain (d) ratio of actual closed loop gain to the ideal value.
