nmos1.sp – DC sweeps of an NMOS transistor
UA741_model.sp – subcircuit macromodel, providing a realistic model of a uA741 op-amp, built with mostly simple linear elements to speed the computation. The input diff pair uses a simple NPN model. Ideal diodes set various limits.
UA741_Inverter.sp – AC analysis of an inverting amplifier using the macro model.
UA741_UnityGain.sp – Transient analysis with the macro model used in a unity-gain configuration.
