An overview of Linear Technology SPICE macromodel library is provided, including the library overview, library usage and the devices in the library
This document serves as an overview of the Linear Technology SPICE macromodel library, intended for analog circuit designers familiar with SPICE and op amp technologies. It discusses the importance of using vendor-supplied models over third-party alternatives to ensure accurate simulation results that match real-world performance.
The text details the Boyle macromodel topology, a standard approach for simulating operational amplifiers efficiently by minimizing transistor counts while maintaining accuracy. It provides key equations for basic model parameters such as gain bandwidth product and slew rate, using the 741 op amp as an example to illustrate nodal conventions and parameter settings.
This document serves as an overview discussion of the Linear Technology SPICE macromodel library for operational amplifiers.
The text assumes the reader has familiarity with the analog simulation program SPICE and modern op amp technologies.
Simulation should be used as a forerunner or supplement to traditional lab testing, rather than replacing breadboarding.
