Figure 1From: Passivity analysis of memristive neural networks with mixed time-varying delays and different state-dependent memductance functions The circuit of memristive neural networks ( 2.1 ). \(x_{i}(t)\) is the state of the ith subsystem, \(\mathbf{R}^{m}_{ij}\) represents the memristor, \(f_{j}\) is the amplifier, \(\mathbf{R}_{i}\) and \(\mathbf{C}_{i}\) are the resistor and capacitor, \(u_{i}\) is the external input, and \(m=1,2,3, i,j=0,1,\ldots, n\).Back to article page
