Classification: CPC H | IPC H

Claim 22:
23. A method for providing a tunable inductance for a multi-gain low noise amplifier (LNA), the method comprising:
providing a first switchable shunting network comprising a first switch in series connection with a first capacitor;
connecting the first switchable shunting network between first and second terminals of a fixed inductance inductor;
connecting the first terminal to a source of an input transistor of the multi-gain LNA; and
connecting the second terminal to a reference ground,
wherein a capacitance of the first capacitor is selected so that at a frequency band of operation of the multi-gain LNA, a parallel combination of the fixed inductance inductor and the first capacitor results in a parallel combined inductive impedance that is larger than an inductive impedance of the fixed inductance inductor.
