Abstract

<div notation="docdba" type="abstract" xml:lang="en"><p>A low voltage level shifter (400) that is suitable for use with subthreshold logic. In one embodiment, the low voltage level shifter includes first and second input transistors (N11, N12) coupled to first and second input nodes (404, 406), respectively, that receive complementary low voltage input signals (in-l, inb-l). A circuit (402) is coupled to the first and second input transistors and to first and second output nodes (414, 412) that generate complementary high voltage output signals. The circuit is configured to transmit a first current (IP12) to the second output node (412) when the first input transistor (N11) is activated, wherein the first current is substantially equal to current drawn by the first input transistor when it is activated. The circuit is also configured to transmit a second current (IP14) to the first output node (414) when the second input transistor (N12) is activated, wherein the second current is substantially equal to current drawn by the second input transistor when it is activated.</p></div>
