Abstract
A system and method is disclosed for adaptively adjusting a duty cycle of a signal between a first and second chip in a 3D architecture/stack for adaptively calibrating a chip in a 3D architecture/stack. In one embodiment, the system includes a first chip and a second chip located within the 3D chip stack, wherein the first chip generates a calibration signal, the second chip receives the calibration signal and compares it to a reference signal to generate a comparison signal that further compared to a reference duty signal to generate a reference duty comparison signal, that is then provided to the first chip to generate a drive signal that adjusts a duty cycle of the calibration signal.
