Abstract
A bi-directional buffer for applications using in an I2C or SMBUS or other bus systems. The bi-directional buffer has an input terminal to receive an input voltage signal and an output terminal for providing an output voltage signal, and the output voltage signal follows the input voltage signal. The output voltage signal is regulated to have a first bias voltage greater than the input voltage signal by a first operational amplifier, or to have a second bias voltage greater than the input voltage signal by a second operational amplifier, the second bias voltage is smaller than the first bias voltage.
