Abstract :
A new approach to power optimization of the sigma delta modulators was presented based on the modeling of noise performance while deciding its system functions and the sub-circuit specifications. And a system model of a 2nd order modulator with a Matlab algorithm to optimize its power specifications was developed. The system simulation results showed that all specifications were consistent with the expectations well. By using the proposed architecture, a resolution of 16-bit was achieved
