Single-phase differential conversion circuit

A single-phase differential conversion circuit, comprising:

• a pair of input terminals and a pair of output terminals and configured to output a positive-phase signal and a negative-phase signal corresponding to an input signal input into one of the pair of input terminals;
• a first differential amplifier including a positive-phase circuit configured to processing a positive-phase signal and a negative-phase circuit configured to process a negative-phase signal;
• and
• a first transmission line having a first end connected to an output terminal of the positive-phase circuit of the first differential amplifier,
• wherein the first transmission line is configured to rotate a phase of the positive-phase signal and reduce an intensity of the positive-phase signal.
