Neuron - Has anyone implemented a electronic (analog) model?

Dear bionet.neuroscience readers,

Mahowald and Douglas described and implemented a silicon neuron
in Nature. (1991: vol 354: 515-518) By using transistor components,
they were able to model the property of neuron firing frequency.
As in Mead's Analog VLSI and neural systems they implemented the
transistors circuits in CMOS VLSI.

I was wondering if anyone out here in bionet.neuroscience have tried to
implement it using discrete components to model a "single" neuron.
Specifically, does anyone know of any commercial transistors having
the same I-V characteristics (i.e. similar sigmoidal shape) as the  
sodium and potassium conductance described in the paper.

I will appreciate any information.

Edwin
