Abstract:
1. An amplifier with three terminals, fabricated on a single chip and having gain and filter performance in a microwave to millimeter-wave range, comprising: an input match unit, used for matching the gain of the amplifier and having a first low pass filter response; a first bias unit, electrically connected to the input match unit, used for driving a first terminal of the amplifier and having a first high pass filter response; a gain stage, electrically connected to the first bias unit, a resistor, a fifth inductor and a first capacitor in series connected between two terminals of the gain stage, used for providing a flat gain of the amplifier; a second bias unit, electrically connected to the gain stage, used for driving a second terminal of the amplifier and having a second high pass filter response; and an output match unit, electrically connected to the second bias unit, used for matching the gain of the amplifier and having a second low pass filter response; where both the input match unit and the output match unit comprise two first inductors with an inductance L wherein both the first bias unit and the second bias unit comprise a fourth inductor with an inductance L
