In the paper the actuality of neurophysiologically motivated neuron arrays with flexibly programmable functions and operations with possibility to select required accuracy and type of nonlinear transformation and learning are shown. We consider neurons design and simulation results of multichannel spatio-time algebraic accumulation - integration of optical signals. Advantages for nonlinear transformation and summation-integration are shown. The offered circuits are simple and can have intellectual properties such as learning and adaptation. The integrator-neuron is based on CMOS current mirrors and comparators. The performance: consumable power 100...500 mu W, signal period- 0.1...1ms, input optical signals power -0.2...20 mu W;time delays - less 1 mu s, the number of optical signals -2...10, integration time -10...100 of signal periods, accuracy or integration error - about 1%. Various modifications of the neuron-integrators with improved performance and for different applications are considered in the paper.

Fast and high-performance vector processors operating in neuro-fuzzy, multivalued, hybrid etc. logics, and structures which implement max/min production of convolution with phasification and dephasification are necessary for hardware decisions of many intelligent problems. We show results of design of such optoelectronic scalar-relation vector processors (SRVP) with time-pulse coding. We consider the concept of such SRVP build-up as base cells for homogeneous 1D and 2D computing mediums. The conception is founded on the use of advantages of time-pulse coding in hardware embodyings of multichannel devices of analog neurobiologic and time-pulse photoconverters. The two-stage structure of the SRVP mapping generalized mathematical model of quasiuniversal map of the relation between two vectors is designed on the basis of the mathematical base which includes the generalized operations of equivalence (nonequivalence), generalized operations of t-norm and s-norm of neuro-fuzzy logic. It is shown that the application of time-pulse coding allows to use quasiuniversal elements of two-valued logic as base blocks on both cascades of the processor. Four-input universal logical elements of two-valued logic (ULE TVL) with direct and complement outputs are used for vectors analog components processing by the first cascade of the SRVP. In a modified variant the ULE TVL have direct and inverse digital outputs for direct and complement time-pulse outputs and are supplied with additional optical signals conversion drivers. The ULE TVL of the second cascade has 2n or 4n inputs, where n - dimension of treated vectors. The circuits of the ULE TVL are considered on the basis of parallel analog-todigital converters and digital circuits implemented on CMOS transistors, have optical inputs and outputs, and have following characteristics: realized on 1.5 mu m technology CMOS transistors;the input currents range - 100nA... 100 mu A;the supply voltage - 3... 15V;the relative error is less than 0

Conference on Enabling Photonic Technologies for Aerospace Applications V

The given paper considers problems dealing with design of optoelectronic trigger devices with optic inputs based on devices with lambda-volt-ampere characteristic including lambda-diodes and lambda-triodes. The paper contains basic parameters and characteristic of lambda-devices, as well as shows factors influencing the choice, change in Aide ranges and regulation of basic parameters of lambda-devices, such as: V=1.5...25V, V-off=1... 15V, I-max=50muA...30mA, I-off=0.1...10nA. The advantage of such triggers is law energy consumption in the mode of logic levels storage (from units up to tenths of nanowatts at V=5V) and voltage of logic levels practically does not differ from potentials of the earth and supply (Deltaapproximate to10muV) such devices enable to be commutated with frequencies up to 360 MHz if the duration of optic pulses t=0.8ns and power 100mW (using photodiodes having responsivity 0.5A/W). That corresponds to the switching energy of 80pJ, average consumption power from supply circuits of 58mW. The decrease of switching frequency at the expense of increase of porosity of supplied pulses and usage of photoreceivers with high conversion efficiency of A/W allows to decrease energy consumption of trigger. Thus, if commutation frequency is 100kHz and duration of optic pulses is 320ns, power - 80muW, that corresponds to switching energy of 26pJ, and usage of photopreceivers having responsivity of 2.5 A/W, the consumed average power of considered optoelectronic trigger from supply circuit is 9muW. That permits to carry out their integration with the number of elements in a matrix is 32x32 and more. We consider simulation results of such optoelectronic triggers based on lambda-devices with different circuits, principles of optical and electronic control and show advantages of such optoelectronic triggers and their multifunctionality.
