Abstract
An output pad for an integrated circuit includes circuitry to align the output with an on-chip clock signal, and to compensate the output such that it remains coincident with the on-chip clock signal even when changes occur in power supply voltage, manufacturing process and temperature. This output pad has a closed-loop feedback circuit which controls the delay of the output signal through a variable delay element. The loop adjust the delay until the clock edge of the on-chip clock signal is coincident with the output signal within a defined tolerance. The output pad self-compensates with every clock cycle, which is many times faster than any induced variation.
