Abstract :
This paper presents a tone free, stable, single loop 3rd order ΔΣ ADC. Performance and stability are obtained through an optimum network scaling based on a novel interactive design methodology. This approach enables for the first time to solve the stability problem in higher order, single loop ΔΣ ADCs without architecture modification and guarantees their full optimization. Simulations of 4th and 5th order structures based on this approach further confirm the efficiency of this method.
