ABSTRACT:
A low to high voltage level converter includes first and second n-channel transistors arranged to force to the ground voltage a first connection node and a second connection node, respectively. A boosting circuit operates to boost an input voltage of at least one of a first and second control nodes for the first and second n-channel transistors above a low voltage level. The converter further includes first and second cross-coupled p-channel transistors arranged to force to the high voltage level the first connection node and the second connection node, respectively. A digital output signal is taken from one of the first and second connection nodes.
