Abstract :
A 3rd order continuous time (CT) Sigma-Delta modulator with a 14-level flash quantizer is presented, which achieves a resolution of 11.2 bit (ENOB) and a SFDR of 84.6 dB for a signal bandwidth of 12.5 MHz according to transistor level post-layout simulations. The proposed solutions limit the total power consumption to 11.3 mW at a supply voltage of 1.2 V with a UMC 0.13 μm CMOS process.
