Abstract

A reconfigurable Sigma-Delta Modulator, which is able to support the various standards of advanced new generation Mobile Technology, is presented in this paper. The system will be able to process more than one signal concurrently. Major Design issues like Area and Power Constraints are outlined and considered in the proper designing of the system. Various configurations are proposed for different technology and the basic building block of the system, a second order low noise Sigma-Delta modulator is designed and simulated in Simulink, Matlab 7.0 with proper consideration of various noises present in the communication channel.
