Abstract
A novel charge-pump phase locked loop (CP-PLL) comprising of a modifie d dual edge sensitive phase frequency detector (PFD) has been proposed . The new structure has an increased loop gain and a faster transient response, although its filter time constant, loop VCO sensitivity and pump current magnitude are same as those of the conventional CP-PLL.
