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 Wnand Vnfrom an input data signal Unand a feedback signal Yn. The generated digital signals Wnand Vncombined may carry the information content of Unwhile they compensate the non-idealities of the two-input analog phase locked loop (PLL). The digital signal Wn, which may be scaled appropriately in frequency, and the digital signal Vnmay be provided as inputs to the PLL. The feedback signal Ynmay be a digital signal that may correspond to the analog feedback signal Ptthat may be generated by the PLL. Accordingly, the PLL may be adaptively controlled via the digital signals Wnand Vnfor properly transmitting the input data signal Un.
