A BiCMOS implementation of the Hodgkin-Huxley formalism

摘要

This paper presents an analog design of a biologically inspired neuron model: the conductance-based Hodgkin-Huxley formalism. After a description of the model equations set, the corresponding subcircuits are detailed. ASICs were fabricated in a 2 /spl mu/m BiCMOS technology, and have a block structure allowing the constitution of complex cells or small networks. As an application, numerical and analog computations of the action potentials are compared, and the effects of some model parameters modifications are shown.
