This paper introduces the multiple model conversion system (MMCSD) to automatically convert the models into hardware description language (HDL) models for either single-input single-output (SISO) or multiple-input single-output (MISO) macromodels and behave as the operational amplifier (opamp). These models are obtained from the multiple model generation system using delta operator (MMGSD). It detects nonlinearity through variations in output error. We demonstrate the application of MMGSD using a two-stage CMOS opamp, comparing simulations of the macromodel against those of the original SPICE circuit utilizing transient analysis. © 2011 IEEE. %Z cited By 1; Conference of 6th International Conference on Design and Technology of Integrated Systems in Nanoscale Era, DTIS'11 ; Conference Date: 6 April 2011 Through 8 April 2011; Conference Code:86189
