1. An electronic network comprising: a plurality of nodes, wherein each node comprises a current input and a current output, and wherein each node further comprises at least one transistor arranged as a first current mirror and a second current mirror, with the first and the second current mirrors being complementary to each other such that an output of the first current mirror is operably connected to an input of the second current mirror; and resistive connections connecting the nodes such that the output of one or more of the nodes is resistively connected to the input of one or more of the nodes.
