CA3046, CA3086, CA3127 Transistor Array SPICE Models
Introduction thor rortio ior)
This application note describes SPICE transistor models bipolar devices that comprise CA3046, CA3086, CA3127 High Frequency Transistor Arrays.
Model Performance
Several model performance curves have been included show accurately models match actual device characteristics. squares shown graphs represent data points taken from data sheet. These data points show that model correlates closely data sheet specifications.
Model Description
While this model developed PSPICE simulator from MicroSim Corporation, adaptable other simulators. performance curves included this document were generated using PSPICE. SPICE simulations should considered substitute breadboarding circuit; rather, they should used select preliminary component values verify validity design approach. This model emulates typical rather than worst case devices, ambient temperature 25oC.
Parameters Modeled
