An amplifier has an open circuit voltage gain of 1000, an input resistance of 2 kQ and an output resistance of 10. Solve the input signal voltage required to produce an output signal current of 0.5A in 40 resistor connected across the output terminals. Fig shows the equivalent circuit of the amplifier. (CLO3, PLO4,CL3) Here A0 = 1000. (15) Rng=12 2 k2 R=42 ces of inverting and non-inverting Analy: Also determine the input and output impedances of the amplifier in given the figure. The op-amp datasheet gives Zin 2MO, Zout = 750, and Aol = 200,000. Also find the closed-loop voltage gain. Ry 220 kn R 10 kn www www
