摘要： A differential sense flip flop (DSFF) that is named the Kulkarni Vrudhula flip flop (KVFF) is disclosed. In one embodiment, the DSFF includes a differential sense amplifier and an SR latch. The differential sense amplifier includes a first amplifier branch having a first output node, a second amplifier branch having a second, a first switchable discharge path, and a second switchable discharge path. The first switchable discharge path is closed to discharge the first output node when first output node is being discharged by the first amplifier branch and the second switchable discharge path is closed to discharge the second output node when second output node is being discharged by the second amplifier branch. This prevents the output nodes from floating and increases the reliability and robustness of the DSFF.

摘要： This disclosure relates generally to threshold logic elements for integrated circuits (ICs). In one embodiment, a threshold logic element has a first input gate network, a second input gate network, a differential sense amplifier, and a resistive network. The first input gate network is configured to receive a first set of logical signals, while the 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 output in accordance with a threshold logic function. The resistive network is coupled between the differential sense amplifier and the first input gate network and between the differential sense amplifier and the second input gate network. The resistive network makes the threshold logic element less susceptible to process variations.
