The document summarizes modeling a 2-input comparator circuit using PSpice. It includes the equivalent circuit diagram showing the two inputs (IN+ and IN-), output (OUT), and components including resistors R1-R3 and capacitor C1. The simulation settings are provided, with two voltage sources (V1 and V2) applying signals of 0V and 5V of varying timing to the inputs to test the comparator output.
