Abstract | ||
|---|---|---|
High-performance phase-locked-loops (PLLs) are key building blocks for many modern ICs. The sub-sampling PLL proposed in [1] uses a reference clock REF to sample a high-frequency VCO and converts phase/timing error into voltage. The steep dv/dt slope of the VCO helps to realize a high phase-detection gain and greatly suppresses the noise of loop components succeeding the phase detector, leading to low in-band phase noise and good PLL Figure-Of-Merit (FOM). However, the original design in [1] is analog and limited to integer-N (int-N) operation. It is desirable to extend it to more versatile fractional-N (frac-N) mode, and to make it digital for greater flexibility and more advanced digital calibration. This work presents a new 28nm CMOS digital frac-N sampling PLL design that achieved 0.16ps rms jitter with 8.2mW and a state-of-the-art frac-N PLL FOM of −246.8dB. |
