Abstract	A noise-shaped pipelined ADC is presented in this paper. A minimal complexity ΔΣ modulator in the first two sub-ADCs and residue feedback in the latter stages lead to high-order noise shaping. This also leads to reduced sensitivity to analog imperfections in the front-end stage. Implemented in 0.18μ m CMOS, the ADC achieves 12 ENOB with 64 MHz clock at 6X OSR while using only a 9-bit linear front-end multiplying-DAC (MDAC). The delta-sigma sub-ADCs dissipate 400μ W extra power (out of 13.9mW total power) while significantly enhancing the the overall ADC linearity.
