Abstract
A method includes providing an active circuit element in a feedback path between an output node and a bypass node of a charge pump of a Phase Locked Loop (PLL). The bypass node is a node to which a charge current or a discharge current is steered to by the charge pump when neither charging the output node nor discharging the output node is required. The method also includes servoing the bypass node to the output node through the active circuit element in the feedback path to maintain a same voltage at the output node and the bypass node when neither the charging of the output node nor the discharging of the output node is required.
