- * Library of Comparator subcircuit definitions
- *
- * This is a reduced version of MicroSim's voltage comparator subcircuit
- * library. You are welcome to make as many copies of it as you find
- * convenient.
- *
- * Release date: 86/01/04
- *
- * The parameters in this opamp library were derived from the data
- * sheets for each part. The comparator macro model used is derived
- * from the op amp macro model used in the OPNOM.LIB file. The op amp
- * macro model is described in:
- *
- * Macromodeling of Integrated Circuit Operational Amplifiers
- * by Graeme Boyle, Barry Cohn, Donald Pederson, and
- * James Solomon
- * IEEE Journal of Solid-State Circuits, Vol. SC-9, no. 6, Dec. 1974
- *
- * The comparators are modelled at room temperature. The macro model
- * does not track changes with temperature. This library file contains
- * models for nominal, not worst case, devices.
- *
- * Although we do not use it, a slightly more elaborate comparator macro
- * model is described in:
- *
- * An Integrated-Circuit Comparator Macromodel
- * by Ian Getreu, Andreas Hadiwidjaja, and Johan Brinch
- * IEEE Journal of Solid-State Circuits, Vol. SC-11, no. 6, Dec. 1976
- *
- * Note: Each macromodel consists of a subcircuit definition AND a set
- * of .MODEL statements. The .MODEL statements should be put into
- * the main circuit file along with the subcircuit definition.
