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. The op amp you select turns out to be non-ideal, and it has a real pole at wC = 1krad/s. Write the updated transfer function for your circuit (using your values of R1, R2, and L = 1H).

Using the components listed below, design an amplifier having a voltage gain of −10 ± 20 percent. The input impedance is required to be as large as possible (ideally, an open circuit). Remember to use practical resistance values. Cascade a non-inverting stage with an inverting stage.1) Standard 5%-tolerance resistors.2) Standard 1%-tolerance resistors. (Don’t use these if a 5%-tolerance resistor will do, because 1%-tolerance resistors are more expensive.)3) Ideal op-amps.4) Adjustable resistors (trimmers) having maximum values ranging from 100 Ω to 1 MΩ in a 1–2–5 sequence (i.e., 100Ω, 200Ω, 500Ω, 1 kΩ, etc.). Don’t use trimmers if fixed resistors will suffice.
For amplifier design, consider a very large load resistance RL . Use a 15 V DC source and a sinusoidal input signal of 200 mVpp and 1 kHz. Hint: you can start by choosing a collector (Icq) or drain (IDQ) operating current between 5 mA and 10 mA. 1. Design an input stage with a common drain amplifier that complies with thefollowing specifications: Voltage gain greater than or equal to 1 (Av1 ≥ 1). Input impedance greater than or equal to 250 kΩ (Zi1 ≥ 250 kΩ). Output impedance less than or equal to 2 kΩ (Zo1 ≤ 2 kΩ). Low cut frequency less than or equal to 20 Hz (fcb1 ≤ 20 kHz).

(a) Design a single-stage inverting ampliﬁer with a gain of 46 dB using an operational ampliﬁer. The input resistance should be as low as possible while achieving the op amp output drive capability mentioned here. The ampliﬁer must be able to produce the signal vo = (10sin1000t) V at its output when an external load resistance RL ≥ 5k Ω is connected to the output of the ampliﬁer. You have an operational ampliﬁer available whose output is guaranteed to deliver ±10 V into a 4-kΩ load resistance. Otherwise, the ampliﬁer is ideal. (b) If the ampliﬁer input signal is vi = V sin1000t, what is the largest acceptable value for the input signal amplitude V? (c) What is the input resistance of your ampliﬁer?
