Multi-band Low Noise Amplifier and Multi-band RF Receiver

摘要

Comprises a multi-band low noise amplifier (multi-band LNA) is part selectively activated and amplified respectively in accordance with a plurality of different frequency bands and degeneration plurality of low-noise amplifier circuit having portions for, for each of the degeneration part inductor included, and the inductors are selected in the inductor current flows only to the low-noise amplifier circuit according to the frequency band, the loop of one of the inductors of which are integrated on the same plane with each other so that the insulation surrounding the loop of the other inductor. Therefore, the chip area can be reduced by reducing the area occupied by the inductor, the inductor can be maintained because current flows selectively, individually FIG inductance and quality factor of the same value as when the integrated respectively.
