摘要
This paper presents a compact and power-efficient 3rd -order CT Delta Sigma ADC with a single OTA. A 4-b fully-passive 2nd-order noise-shaping SAR ADC is employed as the quantizer that inherently provides two additional noise shaping orders. Fabricated in 40nm CMOS, the prototype ADC consumes 1.16mW with a 500MHz clock rate. It achieves a Walden FoM of 17-Wconv.-step and occupies an area of only 0.029 mm(2).
