Abstract
Aspects of a method and system for direct and polar modulation using a two input PLL are presented. Aspects of the system may include generating digital signals Wand Vfrom an input data signal Uand a feedback signal Y. The generated digital signals Wand Vcombined may carry the information content of Uwhile they compensate the non-idealities of the two-input analog phase locked loop (PLL). The digital signal W, which may be scaled appropriately in frequency, and the digital signal Vmay be provided as inputs to the PLL. The feedback signal Ymay be a digital signal that may correspond to the analog feedback signal Pthat may be generated by the PLL. Accordingly, the PLL may be adaptively controlled via the digital signals Wand Vfor properly transmitting the input data signal U.
