Title: poles and zeros in complex RC circuit
Post by hchanda on Oct 5^th, 2007, 9:28pm

All,

How would one intutively find poles and zeros of a complex RC circuit without deriving any mathematical equations?
Please let me know.

Simulate ? :)

You might want to have a look at chapter 8 "Bandwidth Estimation Techniques" of the book by Thomas H. Lee (see http://www.designers-guide.org/Books/#Lee-2003). Another document that might be of interest for you is chapter 3 "Normal & Inverted Poles & Zeros" of R. David Middlebrook's "Design-Oriented Analysis Rules and Tools" at http://www.rdmiddlebrook.com/D_OA_Rules&Tools/index.asp.

Hi,
As Frank pointed in Lee's book there is a good chapter about bandwidth estimation techniques(altough you must do some math), for the method of open circuit time constants if you don't have Lee's book here's the following link:http://ocw.mit.edu/NR/rdonlyres/Electrical-Engineering-and-Computer-Science/6-012Fall-2005/52B44156-E57C-401B-8DAF-923B2E4600F1/0/lec24.pdf
from MIT(after all if I remember well the method was created there).
