LTSPICE_SImulation

design, simulate, build and test a two-stage “mini” op amp. We start with one of the most important amplifier configurations, the differential pair, used for the input stage. Explore the differential amplifier characteristics of gain and impedance in both differential and common mode, and the common mode rejection ratio (CMRR), then add current source biasing and an active load. You will then add an output stage to make the two-stage op amp. The final step will be to add an improvement of your choice. For maximum CMRR, the differential pair transistors should be as identical as possible. Instead of discrete transistors, we will use the MPQ3904 array, which has four npn transistors on one chip. Later, for the active load you will also need two matched pnp transistors. Will provide required model files. To be done in LTSpice and will also need calculations to be done as per requirement.
