Abstract
A level converter comprises first and second latches, and first through fourth transistors. The first latch has first and second power supply terminals, and first and second nodes. The second latch has third and fourth power supply terminals, and third and fourth nodes. The first transistor has a first current electrode coupled to the first node, a control electrode coupled to receive a first bias voltage, and a second current electrode. The second transistor has a first current electrode coupled to the second current electrode of the first transistor, a second current electrode coupled to the third node, and a control electrode coupled to receive a second bias voltage. The third transistor has a first current electrode coupled to the second node, a control electrode coupled to receive the first bias voltage, and a second current electrode. The fourth transistor has a first current electrode coupled to the second current electrode of the third transistor, a control electrode coupled to receive the second bias voltage, and a second current electrode coupled to the fourth node.
