Claim 4:
5. The system of claim 1, wherein the set of adjustable current sources comprises:
a first adjustable current source having a first chopper, a first complementary metal-oxide semiconductor (CMOS) portion, and a second CMOS portion; and
a second adjustable current source having a second chopper, a third CMOS portion, and a fourth CMOS portion, wherein the first chopper and the second chopper are configured to toggle between a first configuration and a second configuration based on a set of chopper clock signals, such that:
in the first configuration, the first sinusoidal current is generated by the first and fourth CMOS portions, and the second sinusoidal current is generated by the third and second CMOS portions; and
in the second configuration, the second sinusoidal current is generated by the first and fourth CMOS portions, and the first sinusoidal current is generated by the third and second CMOS portions.
