Simulation results of optoelectronic photocurrent reconfigurable (OPR) universal logic devices (ULD) as the universal circuitry basis for advanced parallel high-performance processing

Abstract

The conception of construction of the family of the offered optoelectronic photocurrent reconfigurable (OPR) universal or multifunctional logic devices (ULD) consists in the use of a current mirrors realized on 1.5µm, 0.35µm, 65nm technology CMOS transistors. Presence of 44 transistors, 1÷5 photo-detectors makes the offered circuits quite compact and allows their integration in 1D and 2D arrays. The simulation results of the OPR ULD on the 1.5µm, 0.35µm, 65nm technology CMOS transistors showed that the level of logical unit can change from 20nA, 50nA, 500nA 1µA to 10µA for low-power consumption variants and from 20-500nA to 1-10µA for high-speed variants. The base cell of the OPR ULD consist of a small amount of photo diodes, transistors and LED have low power consumption <1µW-5mW. Modeling of such cells in OrCad is made. It is confirmed that all set of possible functions will be realized such OPR ULD by a simple photo-tuning with 10 12 op/s.

“…2. The significant difference of the proposed cell R MCL D from previously considered in papers 25,26 is that for all CL functions formed with TPC signals there is start-stop binding for the start of conversion. For some functions in the same papers 25, 26 such binding was not.…”

“…This shows that in principle it is possible to increase the frame processing rate to 10 MHz, but at the expense of accuracy and complexity of matching photodetectors with current mirrors. The simulation results of similar functionality of universal reconfigurable logic devices with dynamic photodiode controls were shown in paper 26 . It has been shown that for high-speed and simple implementation it is required not the complication of the base cell to improve conversion accuracy, and the analog processing, but the use of electrical signals to select required CL function.…”
