In this paper, the passivity problem is investigated for a class of neural networks with discrete and distributed delays as well as generalised activation functions. By constructing proper Lyapunov-Krasovskii functional and employing a combination of the free-weighting matrix method and inequality technique, a new delay-dependent criterion for the passivity of the addressed neural networks is established in terms of Linear Matrix Inequalities (LMIs), which can be checked numerically using the effective LMI toolbox in MATLAB. Two examples are given to show the effectiveness and less conservatism of the proposed criterion. It is noteworthy that the traditional assumptions on the differentiability of the time-varying delays and the boundedness of its derivative are removed.
