Design a three-stage operational amplifier at the transistor level 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-amp you designed to create an inverting amplifier

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

includes input resistance, output resistance, input bias currents, input offset current, input offset voltage, bandwidth, and slew rate. Provide a table to compare the performance of your op-amp to that of a 741. Use a transistor array (recommended) to build the circuit and test its performance by connecting it in an inverting 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 transistors and conduct the same type of analysis. Compare both designs in terms of their performance characteristics listed above
