摘要：

We present the first millimeter-wave digitally controlled oscillator (DCO) in a 28-nm CMOS technology. This DCO is developed as an integral part of all-digital phase-locked loop for automotive radar applications. The DCO achieves a tuning range of 3.6 GHz (39.3-42.9 GHz) with a fine frequency resolution less than 1 MHz and phase noise of -99.5 dBc/Hz at 1-MHz offset at 39.3 GHz. The DCO occupies 0.08 mm(2) and consumes 10.5 mW. Impacts on DCO design from closely filled dummies to meet extremely stringent local density rules in the 28-nm CMOS process, which has not been investigated before, are also discussed.
