A high-frequency bandwidth amplifier circuit comprises: a push-pull amplifier, a feedback resistor, a first active inductor, and a second active inductor. An input terminal of the push-pull amplifier is connected with an external input terminal. An output terminal of the push-pull amplifier is connected with an output port. A first end of the feedback resistor is connected with the external input terminal. A second end of the feedback resistor is connected with the output port. A first end of the first active inductor is connected with an external power source. A second end of the first active inductor is connected with the output port. A first end of the second active inductor is grounded. A second end of the second active inductor is connected with the output port.
