Design Given the operational Amplifier circuit architecture

Design:

Given the operational Amplifier circuit architecture above, design an operational amplifier (choose R_1, R_2, R_3, R_4 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 lessthanorequalto 600mW VCC=10V, VEE=-10V Bandwidth BW as high as possible (unity gain feedback) Label the inverting and non-inverting inputs to the OP AMP Run a DC simulation and report the power dissipation and compare it with your hand analysis Ground both inputs of the OPAMP and run a DC analysis. Record the value of Vo. Explain what you see and why

Solution

1.an operational amplifier is a dc- coupled high-gain electronic voltage due to negative feedback, the characteristics of an p-amp circuit,its gain,input and output.....this offset voltage can create offset or drifting in the operational amplifer.

(a) while the transfer function(input/output equation) for an operational amplifier with an oper-loop voltage gain of 100,000..... (b)also how to display and interprete simulation results.using a voltage divider example circuit each necessary action is explained step by step (c) identify the device,circuits,and stagesin the 741 operational amplifier
