Diode parameters

Hi!

I need to use a diode in a circuit.
The problem is that I have no idea what to put in its parameters.
I need to define the device area and its perimeter.
Can anyone help me please?

 

I think you have to check the Design Rule Manual tied to the
technology in order get more information on the device.

Dear Sykab,

The size (area-perimeter) of your diode is mainly dependent on your
application. Diodes could be used as Antennas to protect the Gates of
MOS transistors (and other Thin oxide devices) from charging during
the processing of the wafer. Diodes could be used as clamps to protect
internal supplies from large power supply variations and ESD. Diodes
could be used as Power converters in voltage regulators/
converters ...etc. In case of antenna, a minimal diode is usually
sufficient. The rule is set by your Antenna requirements. For clamping
diodes, the size is determined by the amount of Voltage/Current your
ESD protection is designed for. And so on ...

So in addition to your Design Rule Manual (DRM) constraint, please
think about what the diode you're making is designed for.

Hope it helps,

Riad.
