Abstract: The model, algorithm, emulation examples and hardwired circuit based on cosine basis function neural net-work are studied in detail. The emulation results show that the network has an execllent performance with its fast astringercy, and it may be arbitrarily imminent to nonlinear function. In addition, its circuit is easy to be designed because of the simple structure of cosine basis function neural network. All the neural cells are constructed with a single cosine oscillator and a series of frequency multiplier.

Key words: cosine basis function, neural network, circuit design method
