Question

Electrical Engineering

Design a three-stage operational amplifier at the transistorlevel using BJT technology. Your design should

include a differential input stage with large input resistance,a gain stage, and an output stage with low

input resistance. Justify your design choices. Use the op-ampyou designed to create an inverting amplifier

using negative feedback with a given gain, A = −Rf/Ri . Providea characterization of your op-amp design which

includes input resistance, output resistance, input biascurrents, input offset current, input offset voltage, bandwidth,and slew rate. Provide a table to compare the performance of yourop-amp to that of a 741. Use a transistor array (recommended) tobuild the circuit and test its performance by connecting it in aninverting amplifier configuration, and verifying the circuit gain.Compare the experimental results to those obtained using a 741.

Design a two-stage operational amplifier using MOSFET transistorsand conduct the same type of analysis. Compare both designs interms of their performance characteristics listed above
