Abstract

A circuit includes a reference node configured to carry a reference voltage level, a first node configured to carry a signal having a first voltage level or the reference voltage level, a second node configured to carry a power supply voltage having a power supply voltage level in a power-on mode and the reference voltage level in a power-off mode, and a plurality of transistors coupled in series between the first node and the reference node. Each transistor of the plurality of transistors receives a corresponding control signal of a plurality of control signals, and each control signal has a first value based on the power supply voltage in the power-on mode and a second value based on the signal in the power-off mode.
