1. A level-shifter, comprising:
input circuitry configured to receive one or more input signals from one or more input voltage domains;
output circuitry configured to provide an output signal, based on at least one of the one or more input signals, for an output voltage domain, wherein an operating voltage of the output voltage domain is greater than an operating voltage of the one or more input voltage domains; and
a boost circuit connected to the output circuitry and configured to provide a current pulse for a transition edge of the output signal, wherein the input circuitry includes an input transistor stack connected in series with an output transistor stack of the output circuitry.
