An integrated-circuit comparator macromodel

A macromodel for integrated-circuit comparators, suitable for use with typical present-day (1976) circuit simulators, is presented. The macromodel can provide up to an order of magnitude reduction in CPU time and matrix size for CAD. Good agreement (typically within 10 percent) between experimental and macromodel transient response parameters is obtained. A detailed macromodel design procedure is presented that enables the macromodel parameters to be found from typical data-sheet or easily-measured parameters.
