Abstract
A low-power receiver front-end includes a transconductance amplifier that produces a single-ended current signal in response to a single-ended voltage signal. An output of the transconductance amplifier is provided to an LC tuned circuit. At resonance, the LC tuned circuit generates a differential current signal in response to the single-ended current signal. Single-ended current signals corresponding to the resonant frequency of the LC tuned circuit are converted into differential signals. Further, the LC tuned circuit amplifies the differential current signals by an associated quality factor. Further, a mixer is coupled to an output of the LC tuned circuit. The mixer generates IF signals in response to the differential current signals.
