Abstract
An analog belief propagation system uses current mode implementations of storage elements and circuit implementations of at least some nodes of a factor graph using current representations. The system mitigates or avoids effects of non-linearities and approximations in storage and processing elements of the system, for instance, by using storage cells that reproduce current values and using factor circuits that separate control sections and signal path sections of the circuits.
