Abstract
A method and dynamic circuit selectively controls the amount of feedback that is supplied to the dynamic node to provide more feedback when more is needed to enhance functional operation and less feedback when less is needed to enhance performance. The additional feedback inhibits the detrimental effects of charge loss due to leakage and noise mechanisms. The circuit may, for example, selectively control the amount of feedback in response to a test signal. The test signal can be manipulated to cause the circuit to provide more feedback when the circuit is undergoing reliability stress testing and less feedback when the circuit is in normal operation as part of an electronic device.
