Spice macro model. Usage of SPICE Macromodel (for LDO) This application note explains how to install SPICE macromodels (hereafter “SPICE models”) and how the circuit symbols are configured. These models give the designer a tool to do initial character-ization and a limited amount of system troubleshooting. The model comes in the form of a text file that can be imported into the spice program. A more comprehensive SPICE macro model for a current feedback amplifier is developed. SPICE Macro Models Our macro models simulate typical noise, offset voltage, bias current, gain bandwidth, VCA distortion and other important parameters necessary for SPICE modeling. The device models are compacted into one ZIP file for easy downloading. Mar 22, 2018 ยท The SPICE macromodel implementations are simplified groupings of the individual component equations, so the macromodel runs much faster than the design-group simulation and is more robust. This macro model includes effects such as transfer response, accurate AC response, DC offset and voltage noise. . For each new MOSFET that is released by International Rectifier a corresponding Spice model is generated and published. Download Macro Models File Revision 05 All major competitors in the operational amplifier markets are providing their customers Spice-based macromodels. lzaxn ltrbcd uowjn fgsfd sbaj xqphwq nfmk pkqgkb zxtf bdql
