Paper Abstract

We consider design of hardware realizations of optoelectronic reconfigurable universal or multifunctional logical elements of two-valued logic with current inputs and current outputs on the basis of CMOS current mirrors and circuits which realize the limited difference functions. We show advantages of such elements consisting in encoding of Boolean variables by the photocurrent levels, that allows easily to provide optical inputs (by photodetectors) and optical outputs (by light-emitting devices). The conception of construction of the family of the offered optoelectronic photocurrent reconfigurable universal or multifunctional logical elements (OPR ULE) consists in the use of a current mirrors realized on 1.5μm or 0.35 μm technology CMOS transistors. Presence of 15-30 transistors, 1÷4 photodetectors makes the offered circuits quite compact and allows their integration in 1D and 2D arrays. In the presentation we consider the whole family of the offered circuits, show the simulation results and possible prospects of application of the circuits in particular for time-pulse coding for multivalued, continuous, neuro-fuzzy and matrix logics. The simulation results of the NOT, AND, OR, OR-NOT,XOR current logical elements and OPR ULE on the 1.5 μm or 0.35 μm technology CMOS transistors showed that the level of logical unit can change from 1 μA to 10 μA for low-power consumption variants and from 10 μA to 100 μA for high-speed variants. Signals delays, values of fronts and cutoffs at operation with impulse logical signals with 1uA logical unit are not exceed 70-140 ns and at operation with impulse logical signals with 100 μA logical unit are no more than 4-6 ns and the consumption power is 100-4000 μW.
