ABSTRACT:
An apparatus and a method for improving production yield of phase locked loops (PLLs) have been disclosed. One embodiment of the apparatus includes a PLL comprising a charge pump and an offset compensation circuit coupled to the charge pump to provide an offset current to the charge pump to reduce a static phase error of the PLL caused by a mismatch in at least one of a process variation, a voltage, and a temperature. Other embodiments are described and claimed.
