摘要

本文分析了短沟道ＭＯＳＴ阈值电压在室温以上的温度特性，并给出了它的温度系数计算公式。根据计算结果，可以得到如下结论：短沟道ＭＯＳＴ的阈值电压温度系数随着沟道长度缩短而减小．与长沟道ＭＯＳＴ相似，在一定的温区范围内，可以把短沟道ＭＯＳＴ的阈值电压温度系数作为常数，用线性展开式来表达阈值电压的温度特性。

Abstract

This paper analyzes temperature characteristics（27℃ to high temperatures） on short channel MOSFET threshold voltages and gives calculation formulas of their temperature coefficients.From computing results

it may be concluded that with channel length shortening

threshold voltage temperature coefficients of short channel MOSFETs decrease.Like a long channel MOSFET

at a relative wide temperature range

the threshold voltage temperature coefficient of short channel MOSFET can be considered as a constant and a linear expression is used to describe temperature characteristics of threshold voltages.
