In this paper, the passivity problem is investigated for a class of stochastic neural networks with time-varying delays as well as generalized activation functions. By employing a combination of Lyapunov functional, the free-weighting matrix method and stochastic analysis technique, a delay-independent 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. An example is 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.
