Abstract :
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)
