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.
