A phase interpolator, including: a pair of load resistors coupled to a supply voltage; a plurality of branches coupled to the pair of load resistors, each branch including a differential pair of transistors connected at source terminal to form a source node; a plurality of tail current sources, each tail current source coupled to one of the source nodes; and a plurality of coupling capacitors, each coupling capacitor coupled between the source nodes in two adjacent branches of the plurality of branches. |
