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.
