Abstract
A linear but fully digital phase control path and a bang-bang frequency control path enable an energy-efficient digital ring-oscillator PLL architecture. A 65nm CMOS prototype occupies 150μm × 170μm of area and generates a 3GHz clock from a 300MHz reference with 1.13ps rms period jitter while consuming 2mW from a single 1V power supply.
