Abstract
A system for high voltage level shifting includes a level shifting circuit having a high side circuit that receives a mixed signal having a common mode signal and a differential mode signal, and to attenuate the common mode signal in the mixed signal to generate an adjusted signal. The high side circuit generates a high output signal at a high output node in response to the adjusted signal. The system further includes a high side high voltage power transistor having a gate connected to the high output node of the high side circuit. The high side high voltage power transistor configured to provide a high portion of an output signal on a first output node in response to the high output signal.
