Prahlad:

I suggested in another thread that you should look at downloading LTSpice
(see: http://www.8052.com/forum/read.phtml?id=80111 ).

If you should choose that path here is some info to get you started.

The LTSpice Schematic:


The LTSpice Output Waveform:


The LTSpice Data File for this design that you can download and plug right in.
(Make sure to save it as a .ASC file).

From my evaluation of this design it looks like it would be beneficial to use two diodes that are in the same package. The type of BAT54 that has two diodes in series seems like it would be an excellent choice in this circuit.


Have Fun
