Abstract
A level shifter includes: a current pulse generation circuit coupled to a first supply rail and a first (ground) reference rail and configured to output non-overlapping first and second current pulses based on opposite edges of a logic input signal; a latch and a current mirror circuit coupled to a second supply rail and a second reference rail and configured to mirror the non-overlapping first and second current pulses such that the latch is set when the first current pulse is active and reset when the second current pulse is active, the second reference rail; and a voltage headroom circuit configured to mitigate voltage headroom loss between the second supply rail and the first reference rail, independent of an electric potential difference of the second reference rail. A power electronics circuit that includes the level shifter is also described.
