  • Abstract
    An ADPLL which uses a time-to-digital convertor with <;0.13rad resolution achieves LO generation at 3GHz with -104dBc/Hz in-band phase noise. The fine and stable resolution is derived by known phase interpolation circuits. It is fabricated in a 65nm CMOS process and the active area is 0.18mm2.
