Low-cost receiver using integrated inductors

A method comprising:

• receiving a radio frequency (RF) input signal;
• amplifying the RF input signal to form an amplified RF input signal;
• selectively switching the amplified RF input signal to one of a plurality of nodes;
• filtering the amplified RF signal using a selected one of a plurality of filters coupled to respective ones of the plurality of nodes;
• and
• in response to switching the amplified RF signal onto a first of the plurality of nodes, filtering the amplified RF input signal using a first filter of the plurality of filters, wherein the first filter comprises a first variable capacitor coupled in parallel with an inductance leg between a corresponding one of the plurality of nodes and a power supply voltage terminal, wherein the first variable capacitor has a capacitance that varies in response to a tuning signal, and the inductance leg comprising a first inductor in series with an effective resistance, wherein the effective resistance has a value related to an upper cutoff frequency to be tuned by the first filter.
