Abstract
Embodiments of the present invention provide a device for level shifting an input signal. The device includes an output buffer that has: an output node, a p-FET coupled to a high reference voltage, and an n-FET coupled to a low reference voltage. The device also includes two latches. The first latch has a first latch output that drives a gate of the p-FET via an inverting circuit element. The second latch has a second latch output that drives a gate of the n-FET via a non-inverting circuit element. The device also includes a reset signal pulse generator that receives the input signal and generates a reset signal pulse in response to a transition in the input signal. Both of the latches are placed in a reset state by the reset signal pulse.
