Creating the op amp SPICE model from ground-up for simulation is esoteric and often time consuming.
National Semiconductor Corporation has an OrCAD Capture library (nationalhighspeed.olb) and PSPICE (national-highspeed.lib) model library for the industry-leading VIP10™ process high-speed operational amplifiers. These libraries contain behavior models of the LMH series high-speed operational amplifiers and the schematic symbols of op amp. These libraries are available for download from amplifiers.national.com. Libraries are created from OrCAD PSPICE A/D version 9.1 and have been verified to match the performance in the datasheet.
The VIP10 is a high-speed, dielectrically-isolated, complementary bipolar IC process that utilizes deep trench technology on a bonded wafer for complete dielectric isolation and optimal high-speed amplifier performance. Trench technology with bonded wafers helps minimize parasitic capacitance for optimal power-to-bandwidth performance, lower distortion and decreased die size.
