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 0.18- μm CMOS, the ADC achieves 12 ENOB with 64-MHz clock at 6× OSR while using only a 9-b linear front-end multiplying DAC. The delta-sigma sub-ADCs dissipate 400 μW of extra power (out of 13.9-mW total power) while significantly enhancing the overall ADC linearity. |
