ABSTRACT:
A translinear f.sub.T multiplier has a pair of differential transistor amplifiers, each pair having commonly coupled emitters, with the base of one transistor of one pair being coupled to the base of one transistor of the other pair and the collectors of the pair being cross-coupled. A diode network provides three parallel diode paths from a reference voltage, two paths being coupled to receive an input signal and to the bases of the other transistors of each pair and the third path being coupled to a constant current source and to the bases of the first transistors of each pair. The resulting circuit configuration accommodates varying transition times.
