Classification: CPC H | IPC H

Claim 10:
11. An operating method of a phase shifter comprising:
generating a first signal and a second signal, the second signal is having a phase orthogonal to the first signal;
outputting the first signal and the second signal;
converting a first digital signal determining a magnitude of a first current into a first analog signal and a second digital signal determining a magnitude of a second current into a second analog signal;
generating the first current based on the first analog signal and the second current based on the second analog signal; and
performing an operation for the first current based on the first signal the second current based on the second signal,
wherein the performing an operation for the first current and the second current includes:
determining paths of the first current and the second current;
buffering the first current and the second current for which the paths are determined;
summing the first current and the second current;
adjusting the sum of the first current and the second current; and
generating a voltage signal based on a result of the adjustment.
