Abstract
A 90nm CMOS charge-pump PLL incorporates an all-digital auxiliary feedback loop that dynamically detects and compensates the static phase offset. The on-chip monitoring of the static phase offset with a preset target value allows for accurate and reliable compensation. A measured static phase offset as large as 600ps is compensated to a plusmn15ps range.
