Claim 6:
7. The system of claim 1, wherein the set of adjustable current sources comprises:
N adjustable current sources, each configured to output a nominally identical unit current (Iunit) based on the loop control voltage; and
a local current rotator having:
N rotator inputs each to receive the Iunit from a respective one of the N adjustable current sources;
a first rotator output to output the first sinusoidal current to the first branch based on a rotating combination of N-M of the N adjustable current sources; and
a second rotator output to output the second sinusoidal current to the second branch based on a rotating combination of M of the N adjustable current sources distinct from the N-M of the N adjustable current sources,

wherein N is an integer greater than 2, and M is an integer between 1 and N−1.
