(Left panel) The Printed Circuit Board for our 8-cell SPU. (Right panel) Illustration of eight unit cells that are all-to-all coupled to each other, as in our SPU. Each cell contains an LC resonator and a Gaussian current noise source, as shown in the circuit diagram on the top right. The circuit diagram on the bottom depicts two capacitively coupled unit cells.
