Abstract
A level shifter may include a first transistor stack including at least four transistors arranged from a first voltage source to ground, including second and third transistors coupled with bias voltage source, and a fourth transistor coupled with an input to receive an input signal at a second voltage or ground. The level shifter may include a second transistor stack comprising at least four transistors arranged from the first voltage source to ground, including second and third transistors coupled with the bias voltage source, and a fourth transistor to receive an inverse of the input signal. A first transistor of the first transistor stack is cross-coupled with a first transistor of the second transistor stack. A level shifter may include a first output coupled with the second transistor stack between the second and third transistors to provide a first output signal at the first voltage or ground.
