| Abstract(in English) | The theme of the Microwave Circuit Design Universiade 2016 was design and fabrication of a wideband amplifier. There is a negative feedback amplifier as a means for broadening the band of the amplifier. Then, I selected with a method of applying current feedback by adding an emitter resistance to a bipolar transistor，it was confirmed that the gain in the low frequency range could not be suppressed and the fractional bandwidth could not be increased．Thus，a current-feedback pair configulation by using two transistors was adopted．The method was possible to obtain a flat gain even in a high band．Fabricated amplifier obtained 181% fractional bandwidth. |
