Abstract: A receiver includes a first amplifier having an input for receiving an RF signal, and an output for providing an amplified RF signal, a switch section that selectively switches the amplified RF signal onto a selected one of a plurality of nodes, and a filter section comprising a plurality of filters coupled to respective ones of the plurality of nodes. A first filter of the plurality of filters 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. The first variable capacitor has a capacitance that varies in response to a tuning signal. The inductance leg includes 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.

Abstract: An integrated receiver includes a first signal processing path, a second signal processing path, and a controller. The first signal processing path has an input and an output for providing a first processed signal, and comprises a first tracking bandpass filter having a first integrated inductor formed with windings in a first number of metal layers of the integrated receiver. The second signal processing path has an input and an output for providing a second processed signal, and comprises a second tracking bandpass filter having a second integrated inductor formed with windings in a second number of metal layers of the integrated receiver. The second number of windings is lower than the first number. The controller enables one of the first and second signal processing paths corresponding to a selected channel of a radio frequency (RF) input signal to provide an output signal.
