    摘要： In a SAW-less receiver involving a passive mixer, novel degenerative impedance elements having substantial impedances are disposed in incoming signal paths between the differential signal output leads of a low-noise amplifier (LNA) and the differential signal input leads of the passive mixer. The passive mixer outputs signals to a transimpedance amplifier and baseband filter (TIA). Providing the novel degenerative impedance elements decreases noise in the overall receiver as output from the TIA, with only minimal degradation of other receiver performance characteristics. In some examples, the passive mixer receives local oscillator signals having duty cycles of substantially less than fifty percent. In some examples, the degenerative impedance elements can have one of several impedances.

The second transistor has its source coupled to the second inductor, amplifies the input signal, and provides a second amplified signal in a second mode. The third transistor has its source coupled to the second inductor. The first and third transistors receive the input signal and conduct current through the first and second inductors, respectively, in a third mode. The first transistor observes source degeneration from a transformer formed by the first and second inductors, amplifies the input signal, and provides a third amplified signal in the third mode.
