Abstract :
In this paper an analogue current-mode skeletal circuit, that is suitable for the realisation of the Hodgkin and Huxley (HH) nerve axon membrane equations, is presented. The circuit is derived by exploiting the inherent properties of the recently proposed `Bernoulli Cell´ to calculate the continuous intermediate state variables of the HH nerve axon equations. HSPICE simulations confirm theoretical expectations, using weakly inverted MOSTs
