Problem 3: For the figure below. All of the transistors in the simple operational amplifier are matched and have current gains of 100 and VBE = 0.7 V. Vcc = = 5V, Rs = 1052, Rc = 8.6 kq R1 = 1k2 and R2 = 4k02 1. Determine the voltage and current at the DC operating point. 2. Draw the AC equivalent small signal midband for this amplifier. 3. Determine the Midband closed-loop gain. 4. Find the value of the input resistance as indicated in the circuit. 5. Quantify the value for output resistance.
