Abstract
An aging resilient level shifter has an increased lifetime as compared to a conventional level shifter. In at least one embodiment, a method for level-shifting a received signal from a first voltage domain to a second voltage domain includes controlling a cross-coupled pair of transistors according to an input signal and a complementary input signal to generate a signal on a pair of complementary nodes. The cross-coupled pair of transistors has a first doping type and the controlling uses a pair of transistors having a second doping type. The second doping type is complementary to the first doping type. The method includes isolating the pair of transistors from the pair of complementary nodes using a pair of isolation transistors and a pair of cascode transistors. The pair of cascode transistors is coupled between the pair of transistors and the pair of complementary nodes.
