Abstract

A level shifter, configured to shift an input voltage swing from a first voltage range to a second voltage range, comprising a first stage and a switching stage, with circuitry configured in isolation wells. The first stage includes a first stage input receiving an input signal that swings between a first voltage value and a second voltage, a buffer configured to shift the input signal to vary between a third value and a fourth value, and a first stage output configured to present a first stage output signal. The switching stage comprises switching stage inputs, configured to receive the first stage output signal, switch drivers, and switching devices configured to, responsive to the driver output, generate a switching stage output signal that is a shifted version of the input signal. The switching stage output signal ranges between a fifth voltage value and a sixth voltage value.
