Techniques are provided for calibrating on-chip termination impedances on integrated circuits. An on-chip termination (OCT) calibration circuit generates calibration codes that selectively control the conductive states of a set of transistors coupled in parallel. The OCT calibration circuit selects a...http://www.google.fr/patents/US20080061818?utm_source=gb-gplus-shareBrevet US20080061818 - Techniques For Providing Calibrated On-Chip Termination Impedance
