Abstract
A circuit for addressing leakage. The circuit may have a variable supply stage having an active load in parallel with a switch transistor where the active load and the switch transistor are coupled to a decoupling capacitor. The circuit may also have a leakage detect stage having a leak device coupled to a critical node. An embodiment of the circuit may have a supply node; an input node; an output node; a buffer stage where the buffer stage supply node is coupled to a variable supply stage output, the buffer stage input is coupled to the input node and the buffer stage output is coupled to the output node; a leakage detect stage where the leakage detect stage supply node is coupled to the supply node and the leakage detect stage input is coupled to the input node; and a variable supply stage where the variable supply stage supply node is coupled to the supply node and the variable supply stage input is coupled to the leakage detect stage output.
