Abstract: An electronic device includes a phase locked loop configured to perform a two-point modulation operation on a data signal by using first and second modulation paths, and the phase locked loop is configured to generate, based on a differential value of a first phase error signal generated in the first modulation path, a gain for adjusting a frequency variation of the data signal through the second modulation path so as to match with the frequency variation of the data signal through the first modulation path.
