چکیده
This article presents two new, reconfigurable multifunction floating-gate circuit to produce either the INVERTED CARRY function for a FULL-ADDER, an INVERTER, or two-input NAND or NOR gates. The circuits contains two MOSFETs and three or four capacitively coupled input signals. SPICE simulations are shown, demonstrating the principal operation, together with preliminary measurements indicating that the circuit might operate with a supply voltage below 100 mV.

متن کاملA novel design for all-optical NAND/NOR/XOR gates based on nonlinear directional coupler
In this paper a novel all-optical logic NAND, NOR and XOR gate based on nonlinear directional coupler theory is demonstrated. We use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. In other words, while a beam with 4 W/μm in power considered as logical one, the output is NAND gate and if a beam w...

متن کاملExperimental Setup for UV-Programming of Floating- Gate MOS Circuits
In this paper the experimental equipment for UV-programming of floating-gate circuits are presented along with initial results on concurrent UV-programming of digital floating-gate circuits. It is demonstrated that concurrent UV-programming is possible when using real-time reconfigurable gates (Universal Gates). It is also shown that openings in the passivation, enabling UV-programming, works t...
متن کاملFloating-Gate UVMOS inverter
The supply and threshold voltage scaling has been proposed for low-voltage/low-power design [1, 2, 3]. The programmable floating-gate circuits [3, 4] can be used to implement low-voltage/low-power digital circuits. The threshold voltages are shifted using reversed supply voltages and UV-light. The supply voltage may be reduced and the current level is determined by the threshold shift. Before t...
