PRODUCING MODELS FOR DYNAMICALLY DEPLETED TRANSISTORS USING SYSTEMS HAVING SIMULATION CIRCUITS

摘要

A simulation circuit, that simulates characteristics of transistors is produced to include: an isolation body resistor representing resistance of a channel isolation portion of a transistor; a main body resistor representing resistance of main channel portion of the transistor; an isolation transistor connected to the isolation body resistor; and a body-contact transistor connected to the main body resistor. Simulated data is generated by supplying test inputs to the simulation circuit, while selectively activating either the isolation transistor or the body-contact transistor. Test data is generated by supplying the test inputs to the transistors, and measuring output of the transistors. The simulated data is compared to the test data to identify data differences. The design of the transistors is changed to reduce the data differences. The generation of test data, comparing, and design changes are repeated, until the data differences are within a threshold.
