Zener Diode Part List
Recently, I use some zener diode as a reference source to drive my comparator circuit.
So I made a Zener Diode List which from my "Search Job".
Here is the spreadsheet:
1N4099 ~ 1N4135 LOW CURRENT OPERATION 6.8V@250uA IZT LOW REVERSE LEAKAGE AND LOW NOISE CHARACTERISTICS 1N4158 ~ 1N4193 6.8V@37mA IZT
1N4400 ~ 1N4426 6.8V@37mA IZT
1N4614 ~ 1N4627
1N4678 ~ 1N4717
1N4728 ~ 1N4763
1N5225 ~ 1N5281
1N5333B~1N5388B
They are all Zener Diode, which can be easily got the stores. Here is a PDF which covers all diode
Study Notes | Cadence Allegro SPB
After nearly 3.5 years working in Creative, I finaly decided to change a job with more challenge which I never encoutered.
In a new company, I decide to use OrCAD + Allegro to finish all projects. In next 3~4 weeks, I will write some notes about how to use Allegro to draw a PCB Board. Orcad is somebit of easy job for me because of that I've used a lot with the pspice simulation jobs.
Topic which covers: (Updated 2010-03-29)
1. How to draw Component’s footprint in Allegro
2. How to link a Component’s footprint with a schematic's symbol
3. How to Draw a board outline
4. How to Import a netlist from Capture
Study Notes | High Speed PCB Layout Guideline
As you all know, I am a heavy search-depent person which got almost information from Google. So in my last year, I give a present a KeyNote to my colleagues on the Topic of "How to Google Everything".
And as an electronics engineer myself, I also have collected many design rule from Internet. Most of them coming from Semiconductor Corp (TI, NSC, LT, Onsemi, ... ). So here I gave my version of PCB Design GuideLine.
It will be the first one of my series Guide Book called - TGuide Book Series.
So Here is the 1st one. High Speed PCB Layout Guide Book
