Objective of this design project. The objectives of this design project are: (i) To learn how to design a prototype operational amplifier consisting of four stages: Stage # 1: Differential Amplifier; Stage # 2 Floating voltage to Single ended voltage converter; Stage #3: DC Shifter and Stage #4: Emitter Follower.(ii) To learn how to create simulation experiments to verify the design.
