Abstract
The present disclosure relates to a circuit for level shifting of a data voltage from a transmitter. The circuit comprises an inverter logic. The inverter logic comprises a first transistor and a second transistor. The first transistor is connected to a source voltage and the second transistor is connected to ground. A capacitor is connected to an input of the first transistor and configured to drive the first transistor. The capacitor is configured to charge to a charged voltage equivalent to a difference between the source voltage and the data voltage. The second transistor is configured to be driven by the data voltage, thereby level shifting a level of the data voltage to a level of the source voltage.
