Paper Abstract

The given paper considers problems dealing with design of optoelectronic trigger devices with optic inputs based on devices with λ-volt-ampere characteristic including λ-diodes and λ-triodes. The paper contains basic parameters and characteristic of λ-devices, as well as shows factors influencing the choice, change in wide ranges and regulation of basic parameters of λ-devices, such as: V=1.5 25V, Voff=1 15V, Imax=50μA 30mA, Ioff=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 (Δ≈10μV) 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 - 80μW, 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 9μW. That permits to carry out their integration with the number of elements in a matrix is 32×32 and more. We consider simulation results of such optoelectronic triggers based on λ-devices with different circuits, principles of optical and electronic control and show advantages of such optoelectronic triggers and their multifunctionality.
