Abstract: Exemplary embodiments are related to voltage regulators. A device may include a first energy storage element coupled between a ground voltage and an output. The device may also include a second energy storage element coupled to the ground voltage and configured to selectively couple to the output. Further, the device may include a voltage regulator coupled between an input and the second energy storage element.

Abstract: Certain aspects of the present disclosure provide a voltage level shifting circuit employing a low latency, AC-coupled voltage boost circuit, as well as other circuits and apparatus incorporating such a level shifting circuit. Such level shifting circuits provide significantly lower latency compared to conventional level shifters (e.g., latency reduced by at least a factor of two). Offering consistent latency over the simulation corners, level shifting circuits described herein also provide significantly lower power consumption and reduced duty cycle distortion compared to conventional level shifters.
