摘要

提出了一种采用65nm CMOS技术实现的9ghz全数字控制振荡器。这是第一个在9ghz实现的DCO，覆盖GSM/EDGE和UMTS除频段VII以外的所有发送(TX)和接收(RX)频段。它覆盖了6.35 GHz至9.15 GHz的粗调谐范围，该调谐范围由二进制加权可切换电容器实现。相位噪声性能满足GSM/EDGE和UMTS的要求，电流消耗低。

A 9 GHz dual-mode digitally controlled oscillator for GSM/UMTS transceivers in 65 nm CMOS

A 9 GHz fully digitally controlled oscillator implemented in 65 nm CMOS technology is presented. This is the first DCO implemented at 9 GHz which covers all transmitter (TX) and receiver (RX) bands of GSM/EDGE and UMTS except Band VII. It covers a coarse tuning range from 6.35 GHz to 9.15 GHz which is realized by binary weighted switchable capacitors. The phase noise performance meets the specifications of GSM/EDGE and UMTS with a low current consumption.
