Abstract :
A novel second order noise shaping system with a single integrator amplifier is presented. It is based on an error feedback mechanism that consists of two analog and one digital quantizers. A digital signal processing system introduces second order noise shaping on all of the quantization noises. The Matlab/Simulink simulations include various nonideal effects show that the proposed architecture is an excellent candidate for GSM RF receivers.
