Abstract
A level shifter is provided. This level shifter includes a first driver, a second driver, a capacitor, and a common mode circuit. The first driver has a first signal path that is coupled between an input terminal and an output terminal, and the first driver operates in a first voltage domain. The second operates in a second voltage domain and includes a second signal path and latch. The second signal path is coupled between an input terminal and an output terminal of the second driver, and the latch that is coupled to the input terminal of the second signal path. The capacitor that is coupled between the output terminal of the first signal path and the input terminal of the second signal path, and the bias circuit is coupled to the input terminal of the second signal path and operates in the second voltage domain.
