ABSTRACT
Computer-aided simulation is a powerful aid during the design or analysis of electronic circuits and semiconductor devices. Computer-aided circuit simulation is considered an essential step in the design of integrated circuits (IC), because without simulation the number of “trial runs” necessary to produce a working IC would greatly increase the development cost of the IC. The IC itself contains a voltage reference source and operational amplifier. The input to the circuit is a voltage source, applied differentially to the amplifier. The output will be taken differentially across the collectors of the two upper transistors at nodes 2 and 3. Transient analysis is the most powerful analysis capability of a simulator, because the transient response is so hard to calculate analytically. Process and devices simulation are the steps that precede analog circuit simulation in the overall simulation flow.
