BULK GaAs NEGATIVE CONDUCTANCE AMPLIFIERS

Abstract
By taking the negative mobility slope of a three‐slope piecewise‐linear model for velocity vs electric field in n‐GaAs as an adjustable parameter, good quantitative agreement has been obtained with the measured small‐signal admittance parameters of GaAs negative conductance amplifiers. The calculation yields a negative mobility of about 2500–3000 cm2/V‐sec.
