Abstract
An amplifier circuit according to the present invention includes a first block, a second block, a transformer, and a reference node and operates as a negative impedance converter circuit. A circuit configuration formed by a first transistor and at least one first passive component in the first block with respect to a first terminal of the transformer and a circuit configuration formed by a second transistor and at least one second passive component in the second block with respect to a second terminal of the transformer are the same as each other.
