Unity STF | A sigma-delta linearization method

By Poojan Wagh | Published: November 23, 2008
In a previous post, I discussed the trade-offs in linearity of several continuous-time sigma-delta schemes. In this post, I will describe a method that linearizes the sigma-delta noise-shaping filter (NSF). That is, the scheme presented in this article greatly suppresses the linearity requirements on the noise-shaping filter. This method applies to both discrete-time and continuous-time [...]

Example Simulink model & scripts for continuous-time sigma-delta ADC

By Poojan Wagh | Published: September 2, 2008
I've put together a 2nd order continuous sigma-delta Simulink model as a starting point. This is the multi-port feedback configuration (feeds back into input of 1st and 2nd integrators).
