A new 2\times {\rm V}\rm DD-tolerant input/output (I/O) buffer with process, voltage, and temperature (PVT) compensation is proposed and verified in a 90-nm CMOS process. Consisting of the dynamic source bias and gate controlled technique, the proposed mixed-voltage I/O buffer realized by only 1 {\rm xV}\rm DD devices can successfully transmit and receive 2\times {\rm V}\rm DD signal. Utilizing this technique with only 1 {\rm xV}\rm DD devices, the digital logic gates are also modified to have 2 {\rm xV}\rm DD-tolerant capability. With2 {\rm xV} \rm DD-tolerant logic gates, the PVT variation detector has been implemented to detect PVT variations from $2\times {\rm V} \rm DD signal and provide compensation control to the 2\times {\rm V}\rm DD-tolerant I/O buffer without suffering the gate-oxide overstress issue.
