Abstract
This paper describes a macromodeling of operational amplifiers for sound effect circuit design. The modular macromodel of operational amplifiers has been investigated for distortion circuits. The macromodel includes the voltage limiting stage with accurate power supply voltages. The macromodel has been implemented in a circuit simulator and the output voltages are compared with experimental data for a distortion circuit. It is found that the modeling of operational amplifiers with accurate power supply voltages is essential in simulating the output wave.
