Abstract
A level shifting circuit includes a first stage and a second stage. The first stage and second stage are operatively coupled to a first and second power supply. The first stage translates a differential input voltage into an intermediate differential voltage. The second stage translates the intermediate differential voltage into a differential output voltage and provides feedback to the first stage in response to translating the intermediate differential voltage. The first stage reduces current flow between the first and second power supply through the second stage in response to the feedback.
