Abstract
A phase splitter includes: a first signal path; and a second signal path, wherein the phase splitter outputs an internal signal of the first signal path as a first phase signal, and mixes an output signal of the first signal path with an output signal of the second signal path, thereby outputting a second phase signal having a predetermined phase difference from the first phase signal.
Claims19
A phase splitter comprising:
- a first signal path;
- and
- a second signal path,
- wherein the phase splitter is configured to output an internal signal of the first signal path as a first phase signal, and mix an output signal of the first signal path with an output signal of the second signal path, thereby outputting a second phase signal having a predetermined phase difference from the first phase signal.

A phase splitter comprising:
- a first signal path configured to include a plurality of signal nodes for generating a plurality of internal signals and output one of a plurality of internal signals as a first phase signal;
- a second signal path;
- and
- a fan-out controller configured to control fan-outs of the first and second signal paths such that the first second phase signal and a second phase signal are generated by the same fan-out,
- wherein the phase splitter is configured to mix the first phase signal with an output signal of the second signal path, and output the second phase signal having a predetermined phase difference from the first phase signal.
