Fig. 2: Probability-distribution-configurable TRNGs based on multiple MTJs.

a Schematic diagram illustrating the connection of four MTJs to the NI PXIe system through a probe card and adapter board. b Generated random numbers exhibiting a Gaussian distribution. c Error analysis of the Gaussian-distributed random numbers, with the left axis representing KL divergence and the right axis representing the mean squared error. d Neighbor correlation of the Gaussian-distributed random numbers. The color intensity indicates the sample point density, and the concentric circles indicate weak neighbor correlation. e–g Random number generation results for several typical probability distributions: (e) uniform distribution, (f) exponential decay distribution, and (g) user-defined arbitrary distribution.
