ABSTRACT:
A dynamic ECL circuit is provided which drives loads having significant capacitance. The dynamic ECL circuit may utilize single level or multiple level logic and may be configured, for example, as an OR/NOR gate. A capacitor is placed between the base of a current source transistor and a circuit point having a logic level complementary to the output connected to the current source. As logic transitions occur within the circuit and are presented on the output, a transient current will be experienced through the capacitor due to the shift in the complementary level thereby momentarily altering the voltage on the base of the current source transistor. The dynamic alteration of base voltage produces a momentary change in the current through the current source transistor which serves to both speed up the high-to-low transition time and the low-to-high transition time on the output line.
