ABSTRACT:
A circuit for controlling phase includes a first node providing a current responsive to a first clock signal, a first plurality of switch circuits coupled to the first node, a first plurality of current supply sources coupled to the first plurality of switch circuits, respectively, a second node providing a current responsive to a second clock signal, a second plurality of switch circuits coupled to the second node, and a second plurality of current supply sources coupled to the second plurality of switch circuits, respectively, wherein the first node and the second node are coupled to combine the first clock signal and the second clock signal, at least one of the first plurality of current supply sources having a current supply amount different from another, and at least one of the second plurality of current supply sources having a current supply amount different from another.
