A neural network device comprises a first plurality of synapse network capacitors, wherein the synapse network capacitors of the first plurality of synapse network capacitors share a first output terminal. The neural network device further comprises a second plurality of synapse network capacitors, wherein the synapse network capacitors of the second plurality of synapse network capacitors share a second output terminal. Still further, the neural network device comprises a metal shielding disposed between the first output terminal and the second output terminal. The neural network device may be used as part of an artificial intelligence system.
