Abstract
Method and apparatus for fast phase locked loop (PLL) settling with reduced frequency overshoot are provided. During acquisition, a first phase offset signal configured to drive a phase error signal to zero is provided at a first circuit of the PLL. The first circuit may be a time-to-digital converter (TDC) of the PLL. A second phase offset signal configured to offset the first phase offset signal is provided at a second circuit of the PLL. The second circuit of the PLL may be a loop filter at the PLL.
