Abstract: The low voltage to high voltage level shifter has falling-edge 1-shot circuits 34 and 36 coupled to the outputs OUT and OUT_B of cross gate-connected transistors 24 and 26 and pull-down transistors 20 and 22. The falling-edge 1-shot circuits 34 and 36 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 38. The flip flop 38 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.

Abstract: A voltage regulator circuit that provides the current necessary to drive an output driver during transients and maintain low output impedance, while having a much better dropout voltage than a single source follower gain stage includes: an output driver 22; a source follower 34 for controlling the output driver; a localized feedback gain loop coupled to the source follower 34; and an amplifier 24 for controlling the source follower 34.
