N2 - This paper presents behavioural modelling and analysis of Error Feedback (EF) SAR ADCs. The capacitor array model proposed here is based in charge equations, which allows accurate modelling of the feedback in EF-SARs. It also introduces models for the feedback amplifier, including offset, non-linear gain, thermal and flicker noise, as well as sampled kT/C noise for switches and reference noise. The proposed models are implemented and validated in Matlab® Simulink®, showing results with accuracy comparable to transistor-level simulations and simulation times several orders of magnitude faster.
