A pipelined NS-SAR ADC with 1-2 MASH structure is presented. Two-stage pipelined structure consisting of 5-bit NS-SAR and 4-bit NS-SAR ADCs shows 3

-order noise-shaping. To maximize power efficiency, a single operational transconductance amplifier (OTA) is reused for both an integrator for noise shaping and a residue amplifier for pipelining. The measured DR is 80dB when the sampling rate is 83.3MS/s and bandwidth is 6MHz, and power consumption is 3.5mW showing FoM

of 172.3dB. The proposed ADC structure greatly relaxes design requirement of each SAR quantizer, and can achieve high resolution and wide bandwidth with good power efficiency. |
