How to design Quadrature Delta-Sigma ADC ?
Aug 22^nd, 2007, 1:12am

Hi.

I'm now trying to design high order single loop quadrature bandpass delta-sigma ADC.
I know delta-sigma toolbox of MATLAB which was developed by Richard Schreier.
This toolbox is useful for real delta-sigma ADC, but can't be used
for quadrature(complex) delta-sigma.

How to design high order quadrature bandpass delta-sigma ADC systematically ?
Is ther any simple solution for applying delta-sigma toolbox to complex DSM ?

You might want to check the Proceedings of the last ECCTD in Sevilla,Spain for more information about it. Ask me for the original paper and the sourceode if you still need it afterwards.
