All-digital PLLs (ADPLL) based on a ring-oscillator (RO) provide very fast settling, but they suffer from quantization (Q) noise due to discrete tuning of their digitally controlled oscillator (DCO). Although RO charge-pump PLLs (CP-PLL) do not exhibit Q-noise thanks to their continuous VCO tuning, they are quite slow and require huge VCO gain. We propose a hybrid-PLL in 7nm FinFET CMOS that combines the best advantages of ADPLL and CP-PLL with a periodical phase realignment by the reference clock. It covers 0.2GHz-4GHz with 0.619ps integrated jitter and settles in 0.6us.@en
