The authors have developed a silicon neuron that exhibits properties s
imilar to those of the Morris-Lecar neuron. The Morris-Lecar model is
a two-state mathematical model that possesses physiological properties
similar to those of actual neurons. The circuit behaviour is analysed
, based on the geometry of nullclines in state space and analytical re
sults are compared with experimental data for a circuit implemented in
a 2 mu m n-well process.
