ABSTRACT:
Techniques of increasing drive strength and reducing propagation delays of a digital logic circuit through the use of feedback are presented. Logic circuitry operative to receive an input signal of the digital logic circuit and a delayed version of an output signal of the digital logic circuit turns “ON” a supplemental drive transistor for a digital state transition of the output signal. The supplemental drive transistor provides supplemental drive current to the digital logic circuit during the output signal digital state transition, thus advantageously reducing propagation delay and increasing fan-out capability. The logic circuitry turns “OFF” the drive transistor once the output signal digital state transition is complete.
