Abstract
A leakage current reduction circuit comprising a transmission gate, a feedback channel and a controller is placed between a first device supplied with a first voltage potential and a second device supplied with a second voltage potential. The voltage potential mismatch between the first device and the second device may cause a leakage current flowing through the input stage of the second device. By employing the low leakage power detection circuit, a logic high state generated from the first device can be converted into a logic high state having an amplitude approximately equal to the second voltage potential.
