Abstract:
1. An integrated receiver comprising: a tracking bandpass filter having an input for receiving a radio frequency (RF) input signal, and an output, and comprising a variable capacitor having a capacitance that varies in response to a bandpass frequency control signal, in parallel with an integrated inductor; said integrated inductor comprising a plurality of windings formed in a plurality of metal layers; a tunable lowpass filter having an input coupled to said output of said tracking bandpass filter, and an output and having a tuning input for receiving a cutoff frequency signal; and a mixer having a signal input coupled to said output of said tunable lowpass filter, a local oscillator input for receiving a local oscillator signal, and a signal output for providing a converted RF signal, wherein said tracking bandpass filter, said integrated inductor, said tunable lowpass filter, and said mixer are formed on a single integrated circuit.
