Abstract
In some examples, a device includes level-shifter circuitry and biasing circuitry including at least four diodes, wherein each diode of the at least four diodes is electrically connected in series. The biasing circuitry further includes push-pull circuitry electrically connected to at least two diodes of the at least four diodes and configured to generate an intermediate voltage signal. The biasing circuitry is configured to deliver a high-side biasing signal to the level-shifter circuitry based on the intermediate voltage signal and a high-side voltage signal from the at least four diodes. The biasing circuitry is further configured to deliver a low-side biasing signal to the level-shifter circuitry based on the intermediate voltage signal and a low-side voltage signal from the at least four diodes.
