Abstract
A buffer circuit includes a first differential amplifier, second differential amplifier, third differential amplifier, and mixer. The first differential amplifier generates a positive differential signal and a negative differential signal based on an input signal and a reference voltage signal. The second differential amplifier generates a first signal based on the positive differential signal and the negative differential signal. The third differential amplifier generates a second signal having a different phase from the first signal based on the positive differential signal and the negative differential signal. The mixer outputs a signal, generated by mixing the first signal and the second signal, as an output signal.
