【摘要】 本文在ＰＳＰＩＣＥ电路模拟的基础上设计了一套ＧａＡｓＩＣ对阈值电压均匀性要求的计算方法，并计算三种不同ＧａＡｓＩＣ对阈值对电压均匀性的要求，结果表明，ＳＤＦＬ对阈值电压均匀性的要求较低，σＶｔｈ为２１８ｍＶ，ＤＣＦＬ和ＢＤＣＦＬ对阈值电压均匀性要求较高，σＶｔｈ分别为３８ｍＶ和３５ｍＶ．模拟计算还提出：优化和未优化的电路对阈值电压均匀性的要求不同；工艺不同，电路对阈值电压均匀性的要求也不同．这些理论计算分析的结果对ＧａＡｓＩＣ的电路设计和工艺选择均有重要指导意义．更多还原

【Abstract】 A method to calculate the requirement of the uniformity of the threshold voltage in GaAs IC based on PSPICE simulation is presented and three different GaAs ICs are concerned.The result shows that SDFL has lower requirement of uniformity, σV th is 218mV while DCFL and BDCFL have higher requirements, σV th is 38mV and 35mV respectively.Also find that optimized and unoptimized circuits have different requirements,so do different processes.This conclusion is helpful to the circuit design and process choice.更多还原
