Abstract:
A voltage level shift circuit comprises a first pair of transistors and a second pair of transistors. A first transistor of the second pair of transistors is coupled with an input signal terminal. A second transistor of the transistors of the second pair of transistors is coupled with an inverted input signal terminal. The transistors of the second pair of transistors are cross-coupled with the transistors of the first pair of transistors. The voltage level shift circuit also comprises a third pair of transistors. The transistors of the third pair of transistors are coupled with the transistors of the first pair of transistors and the transistors of the second pair of transistors. A first transistor of the third pair of transistors is directly coupled with an output signal terminal and second transistor of the third pair of transistors is directly coupled with an inverted output signal terminal.
