could you please share the design for the step response of Figure4. I could not repeat it!

OK, I combined all 3 posts into a PDF file and attached it to this blog (the file is at the bottom of the page, below the subscribe link). I removed all the transition text between the 3 posts and renumbered the equations and figures so it makes sense but if you find a mistake let me know and I'll fix it and post a corrected file. Thanks for reading!

Neil and David,

I really appreciate the positive comments! What I can do is collect all 3 parts into a PDF file and attach it to this post so that it can be downloaded. I'll post again when I've attached the file.

John, you've written the most useful and instructional piece of information on transimpedance amplifier stability that I have ever read--congratulations.

It would be helpful if customers could print out these three parts as a .pdf file.

John,

An excellent article clearly written. Now, if I can just remember where I read this the next time I need it. Thanks for posting this interesting and practical series.

John,

Very nice series and your approach is different than what I have seen before. I like the new perspective here. If your readers are interested in an automated solution, they should tie into WEBENCH's Photodiode site. You can get into that site on http://www.ti.com and pick the WEBENCH sensors tab on the right and the the photodiode button in the left column of the WEBENCH block.
