Abstract
A level-shifter circuit is adapted for shift an input voltage into an output voltage that is variable between a negative voltage value up to a preset positive voltage level. The shifter circuit includes a first circuit adapted to shift the input voltage into the preset positive voltage level, a second circuit adapted to transfer the preset voltage level to a third circuit connected to a preset negative voltage value. The third circuit is connected to a further voltage at a positive or nil level and is adapted to supply an output voltage to the preset negative level or to the positive or nil level.
