| Abstract | This paper presents a wide-band and energy-efficient 0-1 MASH ΣΔ ADC which is realized based on the pipelined-SAR structure. Composed by a 6b SAR ADC in the 1-stage and a 5b SAR ADC in the 2-stage, with alternate loading capacitors (ALC) reused for error feedback, it realizes an ideal 1-order noise shaping while simultaneously maintaining a high-speed pipeline operation. Fabricated in 65nm CMOS, the prototype consumes 4.5mW from a 1.2V supply with 77dB SNDR over 12.5MHz bandwidth, leading to a 171.5dB Schreier FoM. |
