  • Structure for reduced area active above-ground and below-supply noise suppression circuits
    Patent number: 8196073
    Abstract: A design structure for noise suppression. A design structure has a noise detection unit, a noise suppression unit, and a control unit. The noise suppression unit has an input and an output, wherein the input of the noise detection unit is connected to a signal and generates a signal change at the output if a change in the signal is detected. The noise suppression unit has an input and an output, wherein the input of the noise suppression unit is connected to the output of the noise detection unit and generates a correction to the signal in response to detecting the signal change at the output of the noise detection unit. The control unit has an input and an output, wherein input to the control unit is connected to the signal and turns off the noise suppression unit if a state change is detected in the signal.
