http://www.ceaselessone.com/student Things I learn while living life as per usual Fri, 08 Aug 2008 14:10:31 +0000 http://backend.userland.com/rss092 en I had two really weird dreams last night. In the first one, I stuffed someone's shot in basketball. The weird part? I was playing a sport. Haha j/k. The weird part is that I'm almost positive that I actually swung my real-world arm and hit my bed. This was followed by a ... http://www.ceaselessone.com/student/2008/08/mostly-asleep/ So I was looking at my schedule for this coming semester and some of the times lined up all pretty for me to schedule a nap... So I'm doing biphasic again. I'm also going to be working out and doing something aerobic - a combination that I haven't done for something ... http://www.ceaselessone.com/student/2008/08/biphasing-again-now-with-gratuitous-physical-exertion/ OK. So in my last post I showed a first order Gm-C low pass filter. Now I'll show you how to design your own filter. Let's say we want a filter with the transfer function Vin/Vout=s/(τs+1)2. This is a second order filter that selects for a specific frequency and attenuates ... http://www.ceaselessone.com/student/2008/07/ota-fun-continued/ OK. I'm going to go through two examples. The first one is a first-order low pass Gm-C filter. I'll just show the circuit and then we can analyze and note that it works. Then I'll show you the cooler part - design. We'll write a transfer function that we want to ... http://www.ceaselessone.com/student/2008/07/ota-fun/ So far I've talked about reconfigurable hardware in general and then the specific set-up of the FPAA. Now I'll start talking about what's actually inside the CABs (computaional analog blocks).First there are simple transistors. There's both nMOS and pMOS varieties and you have access to their gate, source and drain ... http://www.ceaselessone.com/student/2008/07/what-im-doing-this-summer-part-3/ All right. Now that you've taken a quick view of reconfigurable hardware, we can look at the FPAA in particular. How is it different from an FPGA? Well the main difference is how information is encoded.Instead of passing information as digital ones and zeroes, analog processing allows you to take ... http://www.ceaselessone.com/student/2008/07/what-im-doing-this-summer-part-2/ So I'm working with FPAAs this summer. What's an FPAA? Well, it's not too inaccurate to say that they're like FPGAs except analog... But in case that doesn't mean much to you, we'll take a quick walk down the:History of Reconfigurable HardwareMany moons ago, somebody thought of the idea of ... http://www.ceaselessone.com/student/2008/07/what-im-doing-this-summer-part-1/ I had far too much stuff on my laptop. I'm sure I still do. I just reimaged because lappy had a fatal... uhmmm... something yesterday. I almost started to go on an installing rampage. But then I chillaxed.I don't need that much stuff.Firefox (with 2 extensions and some chrome editing ... http://www.ceaselessone.com/student/2008/05/spring-cleaning/ I know that a lot of my philosophical babble is just that - babble. And a lot of the rest is common sense. Well, today we will be more or less in the common sense category.There are lots of levels of responsibility for actions. For a long time, I've valued ... http://www.ceaselessone.com/student/2008/04/on-responsibility-for-actions/ So I was organizing a bunch of papers I have and added categories to the whole thing.I'm rather amused at how I function nowadays and thought I'd share. For each paper I have something in a text file like this:Minch99 -Reconfigurable Translinear Analog Signal Processing ... http://www.ceaselessone.com/student/2008/03/organization/
