SIGNAL PROPAGATION CIRCUITRY FOR USE ON INTEGRATED CIRCUITS

Signal transmission circuitry on an integrated circuit ameliorates the effects of possible inequality in rise and fall times of buffer circuits along the transmission circuitry by providing at least one of the buffer circuits as an inverting buffer circuit and at least one other of the buffer circuits as a non-inverting buffer circuit. The invention may be of particular interest for use in clock signal distribution networks on integrated circuits such as programmable logic devices.
