• 論文の詳細を見る

• This work proposes a 10b 100MS/s 1.4mm^2 CMOS ADC for low-power multimedia applications. The proposed two-step pipeline ADC minimizes chip area and power dissipation at the target resolution and sampling rate. The wide-band SHA employs a gate-bootstrapping circuit to handle both single-ended and differential inputs of 1.2Vp-p at 10b accuracy while the second-stage flash ADC employs open-loop offset sampling techniques to achieve 6b resolution. A 3-D fully symmetrical layout reduces the capacitor and device mismatch of the first-stage MDAC. The low-noise references are integrated on chip with optional off-chip voltage references. The prototype 10b ADC implemented in a 0.18μm CMOS shows the maximum measured DNL and INL of 0.59LSB and 0.77LSB, respectively. The ADC demonstrates an SNDR of 53.7dB, an SFDR of 61.5dB, and the power dissipation of 56mW at 100MS/s.
