A 5.0/3.3/1.8-V tolerant I/O buffer implemented using typical CMOS 2P4M 0.35-µm process is proposed in this paper. Unlike traditional mixed-voltage-tolerant I/O buffers, the proposed I/O buffer can transmit and receive signals with voltage levels of 5.0/3.3/1.8 V. By using a stacked PMOS and a stacked NMOS at the output stage and a dynamic gate bias generator providing appropriate control voltages for the gates of the stacked PMOS, gate-oxide overstress and hot-carrier degradation are avoided. Moreover, gate-tracking and floating n-well circuits are used to remove undesirable leakage current paths. The proposed topology can be applied to any technologies with the constraint of VDD
