Given the operational Amplifier circuit architecture above d

Given the operational Amplifier circuit architecture above, design an operational amplifier (choose R1, R2, R3, R4 and assume that beta = infinity) such that the following specifications are met: Open loop Gain Avo= 60dB to 80dB (can pick any value within this range) Power dissipation P_DC lessthanorequalto600mW VCC=10V, VEE=-10V Bandwidth BW as high as possible (unity gain feedback) a. Label the inverting and non-inverting inputs to the OPAMP b. Run a DC simulation and report the power dissipation and compare it with your hand analysis c. Ground both inputs of the OPAMP and run a DC analysis. Record the value of Vo. Explain what you see and why

Solution

Vo= 20

vb = R3/(R3 + R4) * 20

Ib = Isat/( 1+ 2/B)
