Abstract
A level-shiftless transmitter includes a transmitter driver circuit. The transmitter driver circuit includes a first PMOS device, a second PMOS device, a first NMOS device, a second NMOS device, and a sub-circuit. The sources of the first and second PMOS devices are electrically coupled with each other. The gates of the first PMOS and the first NMOS devices are electrically coupled with each other. The gates of the second PMOS and the second NMOS devices are electrically coupled with each other. The sub-circuit is electrically coupled with a voltage domain to provide a voltage lower than the voltage domain to the sources of the first and second PMOS devices.
