I've had some long-standing confusion in this subject and decided to write a paper to attempt to clarify things for myself. I'd be interested to see if others think I'm completely off-track or think my points are valid. http://galois.digitalsignallabs.com/channellengthmodulation.pdf PS: I know there's a lot of sharp, eclectic engineers on comp.dsp, hence my cross-post there. -- % Randy Yates % "And all that I can do %% Fuquay-Varina, NC % is say I'm sorry, %%% 919-577-9882 % that's the way it goes..." %%%% <firstname.lastname@example.org> % Getting To The Point', *Balance of Power*, ELO http://www.digitalsignallabs.com
Channel Length Modulation in MOS Circuit Design
Hi Randy, I went quickly through your pdf this WE, well done ! Well I have any pretension of arguing your equations but I think you know what you're talking about. Anyway, there is one point that would not suit one of my university teachers. He was always getting very upset and angry when seeing the word 'Early' in a MOS-related document. In fact, the similarity in effect between the Early effects in bipolar and channel- length modulation in MOS makes people talking about 'Early' in the MOS world as too. My teacher didn't like it at all ... ;-) But don't worry about it, many people, including myself, are using this mixture. There is a paper on the IEEE that can help you in better understanding and/or cross-checking your results: An exponential model of channel-length modulation applied towards floating-gate circuits http://ieeexplore.ieee.org/Xplore/login.jsp?url=/iel5/7554/20575/00951395.pdf?arnumber=951395 Have fun ! Riad.
