Abstract:
1. A circuit for amplifying a signal, comprising: a transistor operable to receive a signal to be amplified and to generate an amplified signal, the transistor having a source, a drain, and a gate, the gate having a first impedance and operable to receive the signal to be amplified; a transmission line transformer having a first, second, third, and fourth port, the first port and the third port coupled directly to the gate of the transistor, and the fourth port coupled to a source device having a second impedance, the transmission line transformer operable to efficiently transport a signal from the source device to the gate of the transistor by matching the first impedance and the second impedance; and a capacitor having a first end and a second end, the first end coupled to the second port of the transmission line transformer and the second end coupled to a ground.
