Abstract
The low voltage to high voltage level shifter has falling-edge 1-shot circuits and coupled to the outputs OUT and OUT_B of cross gate-connected transistors and and pull-down transistors and . The falling-edge 1-shot circuits and output a narrow pulse when the outputs OUT and OUT_B transition from a high state to a low state. These pulses are used to set and reset a flip-flop . The flip flop provides an output that is only dependent on the very fast fall times of the outputs OUT and OUT_B. This allows the level shifter to be designed for optimal transitional performance without the sacrifice of a potentially long propagation delay on the output nodes.
