Abstract

PURPOSE: To aviod rectifying operation, by keeping the in-phase gain constant, altering only the differential gain, and suppressing the dispersion in impedance of AGC diodes, through the connection of a resistor between the both collectors of a differential amplifying stage and the both emitters.
