Abstract

A transmitter, a common mode transceiver using the same, and an operating method thereof are provided. The transmitter includes a first transistor group and a second transistor group. The first transistor group includes a first transistor connected in series with a second transistor, wherein the second transistor is applied a first well-tracking control. The second transistor group includes a third transistor connected in series with a fourth transistor, wherein the third transistor is applied a second well-tracking control. There is an output node between the first transistor group and the second transistor group, and the second transistor and the third transistor are coupled to the output node. The present invention can effectively block leakage paths in common mode operation, and can enhance ESD protection capability.
