Abstract
A level shifter includes a compact bias generator. The compact bias generator generates a first bias signal and a second bias signal, in the absence of a buffer. The level shifter also includes a first latch in a first stage to translate a first voltage to a second voltage based on the first bias signal. The level shifter further includes a second latch in a second stage to translate the first voltage to a third voltage based on the second bias signal. The first bias signal is independent of the second bias signal.
