A 2.1-GHz dividerless PLL with low power, low reference spur and low in-band phase noise is introduced in this paper. A new phase detection mechanism using aperture-phase detector (APD) and phase-to-analog converter (PAC) generates an analog voltage in proportion to the phase error between reference...
