Low Power Static And Dynamic High Voltage Cmos Level Shifter Circuits

To minimize the area and power overhead typical high voltage sensor interface circuits perform most of the signal processing such as delay and frequency control in low voltage domain following by a level shifter to shift up the signal to high voltage domain as illustrated in fig.
