Techniques for reducing the effects of aging in logic circuits

Abstract:

Logic circuitry includes a first logic circuit, second logic circuits, a third logic circuit, and fourth logic circuits. The first logic circuit inverts a first output signal relative to an input signal only in response to a first control signal having a first state that indicates that the input signal has remained in a same logic state for at least a predefined period of time. The second logic circuits are coupled in series. The second logic circuits generate a second output signal in response to the first output signal. The third logic circuit inverts a third output signal relative to the second output signal only in response to the first control signal having the first state. The fourth logic circuits are coupled in series. The fourth logic circuits generate a fourth output signal in response to the third output signal.
