This paper investigates the passive problem of neural networks with discrete and distributed delays. At first, a novel Lyapunov-Krasovskii functional (LKF) is constructed via introducing a delay-product-type term such that the delay change rate information is abundantly considered. Then, an extended reciprocally convex matrix inequality combined with the Wirtinger-based integral inequality with less conservatism is employed to realize the tight estimation for the derivative of the LKF. As a result, two improved passive criteria for the neural networks with discrete and distributed delays are presented. Finally, two numerical examples are given to show the effectiveness and improvements of our methods."
