In reply to
your question , a diode is usually a semiconductor device
;
though nowadays it can be made from a
few molecules .
The physics can become quite
involved ; I'd like to be able to
model a photodiode . A normal
diode is also sensitive to light .
The diode is a non-linear
device , hence the need to use Newton's
iteration formula .
Apart from the ideal diode
component there is also a complex
impedance , that's modeled in a very
general way by the diode
model I used in the
formula file .
The Voltage Source , Complex
Pixel , partially substitutes for the
complex impedance of the diode
.
Eventually I shall model
this more accurately with a
junction
and diffusion capacitance ,
The frequency response
of the diode , for a particular
amplitude voltage , might then
be obtained by sampling
from a circle , of radius equal
to | amplitude | centered
around the origin
.

Subject: Re: [Fractint] F Diode
' ""After an extended search on the internet and
considerable
testing I'm now able to provide you with a
preliminary model
and fractint formula for a
diode""
Please do - I will check it out. But I am confused. I
remember from my electronics days (a long time ago) a diode is a semiconductor
crystal which lets current flow one way but not the other, so it converts AC
into a pulsing DC current. How does this relate to fractals??
