Abstract

A very simple circuit design of a bidirectional input/output(I/O) buffer is proposed for mixed voltage interface applications. By a floating N-well circuit technique two series PMOS transistors are used as an active pull-up driver. Such a structure provides a simple circuit that requires only a single terminal pad, a single power supply, and is free of DC leakage current. Mixed voltage interface applications such as 3.3V/ 5V are demonstrated.
