In this paper, we propose a novel pulse-coupled neural network (PCNN) simulator using a programmable gate array (PGA) technique. The simulator is composed of modified phase-locked loops (PLLs) and a programmable gate array (PGA). The PLL, which is modified by the addition of multiple inputs and multiple feedbacks, works as a neuron. The PGA, which controls the network connection, works as nodes of dendritic trees. This simulator, which has 16 neurons and 32 32 network connections, is designed on a chip (4.73mm 4.73mm), and its basic operations such as synchronization, an oscillatory associative memory, and FM interactions are confirmed using circuit simulator SPICE.
