Abstract :
A sixth order bandpass delta-sigma A/D converter has been designed and implemented in a 2 μm n-well double poly, double metal CMOS process. The design uses a switched-capacitor cascade-of-resonators topology with half-delay integrators and achieves a SNR of 80 dB over a 0.004π input bandwidth
