Claim 16:
17. The method of claim 13, wherein the generating the first and second sinusoidal currents based on the loop control voltage comprises:
toggling first and second adjustable current sources between a first configuration and a second configuration based on a set of chopper clock signals, such that:
in the first configuration, the generating the first and second sinusoidal currents comprises generating the first sinusoidal current by a first CMOS portion of the first adjustable current source and a second CMOS portion of the second adjustable current source, and generating the second sinusoidal current by a second CMOS portion of the first adjustable current source and a first CMOS portion of the second adjustable current source; and
in the second configuration, the generating the first and second sinusoidal currents comprises generating the second sinusoidal current by the first CMOS portion of the first adjustable current source and the second CMOS portion of the second adjustable current source, and generating the first sinusoidal current by the second CMOS portion of the first adjustable current source and the first CMOS portion of the second adjustable current source.
