Explanation Given Information: Op-amp in noninverting configuration with closed-loop gain 1000 and input offset voltage 3 m V . Output saturation levels are ± 12 V . This indicates the dc power supply used is ± 12 V Calculation: A noninverting based op-amp circuit is shown below. For this circuit, the input gain 1000 and input offset voltage 3 m V . In practical cases, even when the two terminals of the op-amp are grounded, there will be a finite dc voltage appearing at the output which will be either into a positive or negative saturation due to large dc gain of the op-amp. This implies the presence of a dc voltage at the input, which is the input offset voltage which can be negative or positive. Here, it is given as 3 m V . The effect of input offset voltage becomes pronounced when an ac signal is applied at the input. The output obtained will be an amplified ac signal with an amplified version of the input offset voltage which is a dc signal. Hence, if the total output is beyond the saturation voltage of the op-amp, then the ac output can be distorted version. The output of the op-amp is given by Vout=Vout(dc)+Vout(ac) ........ (1) Vout(dc)= output dc voltage due to input offset voltage Vout(ac)=output ac signal due to applied input ac signal a) without capacitive coupling b) with capacitive coupling The output of a noninverting circuit can be written using the general expression as Vout = ( 1 + R2 R1 ) Vin Where ( 1 + R2 R1 ) denotes gain of the noninverting circuit. Here, the two components of output are Vout(dc) = ( 1 + R2 R1 ) Vios Vout(ac) = ( 1 + R2 R1 ) Vin_ac The dc component in total output as obtained above is undesirable can be removed by eliminating the dc component in the input side itself. This can be done by using a capacitor in the input terminal, which blocks dc signals. In this case, the output gets modified as Vout=Vout(ac) = ( 1 + R2 R1 ) Vin_ac ............ (2) The saturation voltage is Vout= ± 12 V Now the maximum amplitude of the signal that can be applied at the input so that output is not distorted is to be found in the cases with and without a capacitor at the input

Multistage Amplifier

The multistage amplifier is generally a voltage or power amplifier. The multistage amplifier has a number of single stage amplifier that are cascaded together. Since a single stage amplifier output is not useful, they are being replaced with multistage a…
