Abstract :
Stability analysis of high-order delta-sigma loops is a challenge. In this work, a novel design criterion is presented for high-order multibit error-feedback DACs which are especially suitable for high-speed operation. This criterion allows the design of stable, robust, and high-resolution delta-sigma DACs. Both analytical and numerical analysis are performed for verification.
