Two-quadrant multipliers are required for several neural network architectures. The efficient implementation of these architectures in silicon requires the development of small, compact, reliable and accurate hardware multipliers. This paper details simulation and hardware results for the DYnamic Mirror PuLsed Experimental Synapse (DYMPLES) Chip. DYMPLES is an analogue current mode chip which utilises dynamic current mirrors and current matching to implement two quadrant multiplication based on the pulse stream approach[1]. HSPICE simulations indicate that the DYMPLES circuits produce excellent current matching and this is reinforced by the hardware results.
