差動増幅装置

Japanese Patent JP7286031

B2

A differential amplification device is configured to include: a first transistor (1-1) that has a first terminal (1-1a) and a second terminal (1-1b), amplifies a first signal provided to the first terminal (1-a), and outputs the amplified first signal to the second terminal (1-1b); and a second transistor (1-2) that has a third terminal (1-2a) and a fourth terminal (1-2b), amplifies a second signal as a signal indicating a differential with the first signal when the second signal is provided to the third terminal (1-2a), and outputs the amplified second signal to the fourth terminal (1-2b). Further, the differential amplification device is provided with: a first resonator (2-1) that extracts, from the first signal output to the second terminal (1-1b), a harmonic in a reverse phase to a harmonic contained in the second signal provided to the third terminal (1-2a) and outputs the harmonic in the reverse phase to the third terminal (1-2a); and a second resonator (2-2) that extracts, from the second signal output to the fourth terminal (1-2b), a harmonic in a reverse phase to a harmonic contained in the first signal provided to the first terminal (1-1a) and outputs the harmonic in the reverse phase to the first terminal (1-1a).
