ABSTRACT:
An integrated circuit including a primary operating circuit and an added-function circuit which reduces propagation delays during normal operation of the primary operating circuit, the primary operating circuit includes an input and an output, an associated voltage source and ground, a transistor positioned on the path from the voltage source to the output and a second transistor positioned on the path from ground to the output, the added-function circuit includes two transistors, each of which is coupled to a transistor of the primary operating circuit on the path from either the source or ground to the output, and the added-function circuit transistors have widths of at least two times the size of the primary operating circuit transistors such that when the added-function transistors are enabled, a pseudo-voltage source and a pseudo-ground are generated for the primary operating circuit transistors to reduce propagation delays in the primary operating circuit based on the added-function circuit.
