Present implementations can include a system with a transistor array including a plurality of charge-trap transistors, the charge-trap transistors being operatively coupled with corresponding input nodes, and a neural integrator including a first integrator node and a second integrator node operatively coupled with the transistor array, and generating an output corresponding to a neuron of a neural network system. Present implementations can include a neural integrator with a first integrator node operatively coupled with a first charge-trap transistor of a transistor array, a second integrator node operatively coupled with a second charge-trap transistor of the transistor array, the second charge-trap transistor being operatively coupled with the first charge-trap transistor, and a capacitor operatively coupled with the first integrator node and the second integrator node, and operable to generate an output based on a first voltage at the first integrator node and a second voltage at the second integrator node.
