ABSTRACT:
Circuits, such as a cascode amplifier or low noise amplifier, having terminals and a voltage-controlled and variable inductive load are disclosed. Any such circuit comprises an output terminal and a voltage-controlled and variable inductive loading network. The voltage-controlled and variable inductive loading network comprises a primary inductor having a first primary inductor terminal for coupling to a supply voltage, a second primary inductor terminal coupled to the output terminal, a secondary inductor sharing mutual inductance with the first inductor, and a variable resistance device having one terminal connected to a first secondary inductor terminal and another terminal connected to a second secondary inductor terminal, wherein the variable resistance device being dependant on mutual induction between the primary and secondary inductors provides loading at the output terminal.
