  • Systems and methods providing a matching circuit that bypasses a parasitic impedance
    Patent number: 10491172
    Abstract: A circuit including a radio frequency (RF) amplifier including a transistor configured to receive an RF signal at its control terminal, a capacitor coupled to a first terminal of the transistor, an inductor coupled to a second terminal of the transistor, wherein the capacitor and inductor form a loop from the first terminal to the second terminal, wherein the loop bypasses a parasitic inductance between the second terminal and ground.
    Type: Grant
