Functional transformation of random signals in a composite magnetoelectric cell

Results of calculations of transfer functions for a composite magnetoelectric cell exposed by random sequences of pulsed signals are reported. Threshold conditions are found for generation of single spikes and random sequences of pulses with fixed amplitude using a combined numerical-analytical method. Probability of switching between the states of the magnetic system is controlled by the magnetization field. Effects of accumulation and threshold-type change of state with switching of polarization like “Integrate-and-fire” behavior are demonstrated for unipolar and bipolar sequences of random input signals. It is shown that in the case of bipolar input signals a steady generation of a stochastic spike sequence is obtained with a random delay of the magnetic subsystem in stable states. The results are aimed at applications in the domain of development of stochastic neuromorphic systems.
