摘要

本文提出了一种0.18 μm CMOS超宽带(UWB)频率合成器，采用数字频率校准技术生成GSM直接转换应用中的所有载波频率，该载波频率可以在最接近目标频率的频带内改变调谐曲线，从而在GSM直接转换应用和MB-OFDM超宽带通信中降低VCO增益KVCO，实现相位噪声和杂散性能的优化。

Frequency synthesizer with digital calibration in a GSM directs conversion application and MB-OFDM UWB communication

This paper presents a 0.18 μm CMOS Ultra wide band (UWB) frequency synthesizer with digital frequency calibration technique to generate all the carrier frequencies for GSM direct conversion application which can vary the tuning curve in the closest band to a target frequency, then, the technique can reduce the VCO gain KVCO and achieve optimized phase noise and spur performance in a GSM directs conversion application and MB-OFDM UWB communication.
