Abstract

A 10bit, 20MS/s pipeline ADC is proposed for ZigBee transceiver in this paper. Due to demand of low power, a multiple sharing technique involved operational operational amplifier (opamp) and comparator is proposed, traditional S/H circuit is cancelled, a new gain boosting switch which could achieve sample and hold in first stage is also proposed. Implemented in a 0.18μm CMOS process, only 19.6mW power consumption from 1.8V power supply is achieved. SNR and SFDR are 61.5dB and 66.24dB, respectively, when a 1MS/s sinusoid signal inputs to the ADC at 20MS/s sampling rate. Particularly the test results show this pipeline ADC is suitable for a low power consumption ZigBee system.
采用多路共享技术的ZigBee收发器低功耗CMOS流水线ADC
本文提出了一种用于ZigBee收发器的10bit、20MS/s流水线ADC。针对低功耗的要求,提出了一种由运算放大器和比较器组成的多重共享技术,取消了传统的S/H电路,并提出了一种新的增益提升开关,实现了一级采样和保持。采用0.18μm CMOS工艺,1.8V电源功耗仅为19.6mW。当1MS/s正弦波信号以20MS/s采样率输入ADC时,信噪比和SFDR分别为61.5dB和66.24dB。具体测试结果表明,该流水线ADC适用于低功耗的ZigBee系统。
