In this paper, we propose a 60-GHz fractional-N digital frequency synthesizer aimed at reducing its phase noise (PN) at both the flicker (1/f <sup>3</sup> ) and thermal (1/f <sup>2</sup> ) regions while minimizing its power consumption. The digitally controlled oscillator (DCO) fundamentally resonates at 20 GHz and co-generates a strong...

To characterize an on-chip programmable delay in a low-cost and high-resolution manner, a built-in self-test based on a first-order &amp;#x0394;&amp;#x03A3; time-to-digital converter with self-calibration is proposed and implemented in TSMC 28-nm CMOS. The system is self-contained, and only one digital clock is needed for the measurements. A...
