Cellular Neural Networks (CNNs) [1] are constructed by cells connected each other. The cell contains linear and nonlinear current sources controlled by voltage. It is known that two-layer CNNs can exhibit oscillation by choosing an appropriate set of the parameters. In this work, we present that a simplification of CNN constructed by two cells can be described by van der Pol equation. Moreover, we confirm the generation of the phase propagation phenomena, which can be observed in coupled van der Pol oscillators , in the two-layer CNNs by computer simulations. We discuss the similarity between the two-layer CNNs and coupled van der Pol oscillators.
