Abstract :
This paper presents a new tracking circuit design without standby leakage current issue for 2.5V/3.3V tolerant I/O buffer, which is suitable for the I/O cells in the mixed-voltage applications with different driving capabilities. One set of mixed-voltage I/O cell with the new proposed 2.5V/3.3V tolerant I/O buffer circuit has been designed and drawn in a 0.13-mum salicided CMOS process. The new tracking circuit can be also applied in other CMOS processes to serve different mixed-voltage I/O interfaces
