摘要:
An output driver for high performance integrated circuits. The driver dynamically compensates for variations in temperature, voltage and process. To perform the compensation, the driver is divided into two parts: static and transient. The static part is used to maintain the DC level. The transient part is active only during logic 0 to 1 and 1 to 0 transitions and is used only to assist the static part during such transitions. A closed loop feedback technique is used to compensate the driver for temperature, process, and voltage variations; specifically, a scaled down version of an output driver is used to monitor speed variations due to temperature, process, and voltage, the output of which is fed back to the output driver which then performs the necessary compensation.
