Abstract
A power-down signal generating circuit receives first and second supply voltages, where the first supply voltage is less than the second supply voltage, and generates a power-down signal. The power-down signal generating circuit includes a driving amplifier, first through third transistors, and an amplification circuit. When the first supply voltage is deactivated, the power-down signal is activated. The driving amplifier prevents the first through third transistors from being enabled simultaneously, which reduces static leakage current.
