Abstract

A 6th order RF bandpass SigmaDelta ADC operating on the 2.4 GHz ISM band is presented. The bandpass loop filter is based on digitally programmable Gm-LC resonators. By using a mirrored-image sampling technique, the clock frequency is reduced to 3 GS/s, thereby reducing the power consumption. Implemented in a standard 90 nm CMOS process, the IC achieves 40 dB and 62 dB of SNDR and SFDR respectively on a 60 MHz bandwidth with 40 mW of power consumption.

2.4GHz 40mW 40dB SNDR/62dB SFDR 60MHz带宽镜像RF带通ΣΔ ADC，采用90nm CMOS

介绍了一种工作在2.4 GHz ISM频段的六阶射频带通SigmaDelta ADC。带通环滤波器是基于数字可编程的Gm-LC谐振器。通过采用镜像采样技术，时钟频率降低到3gs /s，从而降低了功耗。该集成电路采用标准的90 nm CMOS工艺，在60 MHz带宽和40 mW功耗下分别实现了40 dB和62 dB的SNDR和SFDR。
