ABSTRACT:
A voltage level shift circuit has a first input receiving a first voltage signal and a second input receiving a second voltage signal. The voltage level shift circuit is structured to generate an output voltage at an output terminal which is equal to a sum of the first and second voltage signals. The first voltage signal may be varied to vary a shift of the second voltage signal.
