摘要
本文介绍了一种采用65纳米CMOS工艺实现的单通道8位0.7-GS/s a /D转换器的原型。所需的阈值由嵌入在锁存器之前的前置放大器内的电阻插值产生。芯片的有效面积为150 × 220 μm2,总功耗为5.96 mW。在奈奎斯特,ADC达到6.62 ENOB,其优点等于86.7 fJ/转换步长。
An 8-bit 0.7-GS/s single channel flash-SAR ADC in 65-nm CMOS technology
This paper presents the prototype of a single channel 8-bit 0.7-GS/s A/D converter implemented in a 65-nm CMOS process. The required thresholds are generated from the resistive interpolation embedded within the preamplifier preceding the latches. The active area of the chip is 150 × 220 μm2 and the total power consumption is 5.96 mW. At Nyquist, the ADC achieves 6.62 ENOB, resulting in a figure of merit equal to 86.7 fJ/conversion-step.
