My General Purpose SDR I'd like to build a SDR someday, but first there is some design space exploration to be done. This repository holds various circuits that I stumbled upon and that I wanted to simulate. Every Circuit comes as an .asc file that I generated using LTSpice or as a simple SPICE netlist. If you 'd like to participate feel free to do so. Please do _NOT_ share any circuits that you found in some companies reference manual etc... This is about enjoying the technology and fooling around with it. There are pretty amazing things to be discovered and explored like e.g. thermal noise cancellation [1]. Why LTSpice? - cause I like it - it can be downloaded free of charge - it is quite fast - it runs on linux using wine (faster than on my Win7) Bastian Mueller 09/01/2010 --- [1] Bruccoleri, Federico Wideband low noise amplifiers exploiting thermal noise cancellation / by Federico Bruccoleri, Eric A.
