摘要

数字控制LC振荡器(DCO)集成在数字65纳米CMOS技术中。频率可以用10b在9.87 ~ 10.92GHZ(10%)范围内进行微调，频率步长为1.03MHz/LSB。DCO从1.1V电源中吸收3.0mA，在1MHz偏移(FOM=-177.2dBc/Hz)时实现-102dBc/Hz的相位噪声。

A 10b 10GHz digitlly controlled LC oscillator in 65nm CMOS

A digitally controlled LC oscillator (DCO) is integrated in a digital 65nm CMOS technology. The frequency can be fine tuned with 10b from 9.87 to 10.92GHZ (10%) with a frequency step of 1.03MHz/LSB. The DCO draws 3.0mA from a 1.1V supply and achieves a phase noise of -102dBc/Hz at 1MHz offset (FOM=-177.2dBc/Hz)
