Abstract
In one form, an integrated receiver includes a tracking bandpass filter, a tunable lowpass filter, and a mixer formed on a single integrated circuit chip. The tracking bandpass filter has an input for receiving a radio frequency (RF) input signal, and an output, and comprises a variable capacitor having a capacitance that varies in response to a bandpass frequency control signal, in parallel with an integrated inductor. The integrated inductor comprises a plurality of windings formed in a plurality of metal layers. The tunable lowpass filter has an input coupled to the output of the tracking bandpass filter, and an output and having a tuning input for receiving a cutoff frequency signal. The mixer has a signal input coupled to the output of the tunable lowpass filter, a local oscillator input for receiving a local oscillator signal, and a signal output for providing a converted RF signal.
