Floating-gate low-voltage/low-power linear threshold element for neural computation

We present analysis, simulation and measurements, for a new reconfigurable 2-MOSFET linear threshold element and show how it can be used to implement INVERT, NAND3, NAND2, NOR3, NOR2 and CARRY. The threshold, and thereby the Boolean function, might be changed in real time by changing the voltage on one or more of the inputs. Simulation suggests that it can function as a generator of CARRY for binary addition with a power supply voltage down to about 200 mV.
