Abstract
A wireless communication system includes: a switching capacitor; a multi-way switch, having at least a first voltage input port, a second voltage input port, and an intermediate voltage input port, coupled to the switching capacitor; and a CORDIC processor, coupled to the multi-way switch, configured to select the first voltage input port, the second voltage input port, or the intermediate voltage input port.
