Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output pin and two input pins. The basic role of an opamp is to amplify the voltage difference between the two input voltages. It is also used in filtering or to perform mathematical operations or in signal conditioning.

The open-loop gain A of real (nonideal) op-amps isvery large at low frequencies but decreases markedlyas frequency increases. As a result, the closed-loopgain of op-amp circuits can be strongly dependent on frequency. Determine the relationship between a finiteand frequency-dependent open-loop gain AV(OL)(ω)and the closed-loop gain AV(CL)(ω) of an invertingamplifier as a function of frequency. Plot AV(CL)versus ω. Notice that −RF/RS is the low-frequencyclosed-loop gain.
Consider the active circuit with the schematic:a. Assuming it's an ideal op amp, derive the circuit’s transfer function as a function of frequency, H(jw). Make sure it in canonical form.b. We want a DC gain of 40dB. If the op amp has value of Rin = 10MΩ and Rout = 50Ω, choose appropriate values for R1 and R2. Explain why your selected values of R1 and R2 allow you to ignore Rin and Rout for the remainder of the problem. c. If L = 1H, sketch the straight-line approximation of the Bode plot for the circuit’s gain assuming the op amp can still be considered as ideal.d.
