Abstract
A voltage controlled amplifier which includes a gain core and a transconductive amplifier. The gain core includes two complimentary differential transistor pairs. The emitters of the four transistors of the two differential pairs are connected to complimentary diode connected transistors. The diode connected transistors balance the parasitic resistances of the dissimilar transistors, thereby, reducing differential gain and distortion.
