摘要

提出了一种适用于多频段多模式收发器的柔性模数转换器。它可以在管道和DeltaSigma架构之间重新配置，分别在WLAN/WiMAX和GSM/CDMA2000/WCDMA中实现功率优化操作。使用电压缩放和闭环opamp设计技术，在1.2 V电源下，最大动态范围为76 dB，小于1 mW。该原型机采用0.13 mm的CMOS，有源芯片面积为0.43 mm2。

A 1.2V Programmable ADC for a Multi-Mode Transceiver in 0.13μm CMOS

A flexible ADC for a multi-band and multi-mode transceiver is presented. It can be reconfigured between pipeline and DeltaSigma architectures for power optimum operation in WLAN/WiMAX and GSM/CDMA2000/WCDMA, respectively. A maximum dynamic range of 76 dB with less than 1 mW at 1.2 V supply was achieved using voltage scaling and closed-loop opamp design techniques. The prototype was built in 0.13 mum CMOS and the active die area is 0.43 mm2.
