Title: Is anybody know ASIDES for sigma delta design Post by chungmnig on Jul 23rd, 2006, 11:34pm Hi~~~ I looked the book & paper "Top-Down Design of sigma delta Modulator" written by Fernando Medeiro. They introduce Tools ASIDES , SDOPT & FRIDGE for simulate SDM ,it seems very accuracy. Is anybody know that tools? Is it really very useful? I didn't see any people use that except they. And i very wonder how should we choose the opa's specification DC gain ,slew rate......(if we use switched-cap) ? Is just calculated by hand, or use verilog A to model ? I want know a good company how to do this... Thanks~~~!!!!!!!! |

Several years ago I asked them for evaluation copy, but they did not respond, so I gave up.. Actually all equations for modelling non-idealities are in the book, so it's pretty straight forward to implement your own SDM model in Matlab or Verilog-A. Also have a look at a paper & Simulink library by people from Uni of Pavia in Italy (Maloberti & Co) - it's good for a start. |

And you said "Actually all equations for modelling non-idealities are in the book, so it's pretty straight forward to implement your own SDM model in Matlab or Verilog-A" did you do this ? Is it accuracy? thanks~~!! |
