Abstract
A receiver includes a first amplifier, a first variable capacitor, and an inductance leg. The first amplifier has an input for receiving a radio frequency signal, and an output. The first variable capacitor has a first terminal coupled to the output of the first amplifier, a second terminal coupled to a power supply voltage terminal, and a control terminal for receiving a tuning signal. The inductance leg has a first terminal coupled to the output of the first amplifier, and a second terminal coupled to the power supply voltage terminal. The inductance leg includes a first inductor and has an effective resistance in series with the first inductor, wherein the effective resistance has a value related to an upper frequency threshold to be tuned by the receiver.
