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~~~!!!!!!!!
