AMPLIFIER CIRCUIT

Abstract: an amplifier circuit includes a divider that divides an input signal into a first signal and a second signal, a first amplifier that hags a first node receiving the first signal, amplifies the first signal received at the first node, and outputs an amplified first signal as a third signal, a second amplifier that has a second node receiving the second signal, amplifies the second signal received at the second node, and outputs an amplified second signal as a fourth signal, a path that connects the first node to the second node in a direct-current manner via the divider, and a combiner that combines the third signal and the fourth signal. the path is provided with a third node at one location to supply a bias voltage to the first amplifier and the second amplifier.
