Abstract

Low impedance and temperature compensation are desirable characteristics of a bias source to be used with a transistor SSB linear amplifier. Low impedance to prevent shift in operating point with changes in drive and temperature compensation to hold the operating point over the temperature range. The following circuit satisfies both requirements with the ability to adjust the slope (MVI'C) to match the linear amplifier operating condition.
