Abstract
A level shifter circuit for level shifting voltages of signals crossing multiple circuit domains includes an input stage and a driver stage. The input stage receives an oscillating signal generated by a ring oscillator and generates an inverted oscillating signal. The differential oscillating signals are provided to the driver stage, which level shifts a voltage level of the oscillating signal to a level of a supply voltage of the ring oscillator.
