Abstract
A cascaded thin-oxide N-Well voltage steering circuit includes a reference voltage generator that outputs a reference voltage within a range of first and second supply voltages, a first voltage steering circuit that outputs a higher available one of the reference voltage and the second supply voltage as an interim voltage, and a second voltage steering circuit that outputs a higher available one of the first voltage and the interim voltage at an output of the second voltage steering circuit. The interim voltage is applied to N-wells of PMOS transistors of the first voltage steering circuit. The output of the second voltage steering circuit is applied to N-wells of PMOS transistors of the second voltage steering circuit. The output of the second voltage steering circuit may also be applied to N-wells of PMOS transistors of other circuitry. The cascaded thin-oxide N-Well voltage steering circuit may consist substantially of thin-oxide PMOS transistors.
