THRESHOLD LOGIC ELEMENT WITH STABILIZING FEEDBACK

摘要

Threshold logic elements and methods of operating the same are disclosed. In one embodiment, a threshold logic element includes a first input gate network configured to receive a first set of logical signals, a second input gate network configured to receive a second set of logical signals. The differential sense amplifier is operably associated with the first input gate network and the second input gate network such that the differential sense amplifier is configured to generate a differential logical output in accordance with a threshold logic function. In order to make the threshold logic element more robust, the differential sense amplifier is configured to feed back the differential logical output to the first input gate network and the second input gate network. By providing the differential logical output as feedback, floating node issues are avoided and the threshold logic element is more resistant to noise.
