Abstract
A new architecture for a multistage bandpass sigma-delta modulator which tolerates imperfections in the resonator function is proposed. The architecture involves using a FIR filter to reduce the non-cancellation of the quantization noise of the first stage resulting from circuit non-idealities. Computer simulations of two differents structures illustrate the superiority of the new architecture and confirm its ability to withstand reasonable circuit non-idealities
