| Zusammenfassung: | The invention provides a multi-mode receiver radio frequency front-end system and a signal receiving method thereof. The method comprises the steps that a low-noise amplifier works at a high frequency band, and load inductance of the low-noise amplifier is set as L1, wherein L1 is a natural number; and the low-noise amplifier works at a low frequency band, and load inductance of the low-noise amplifier is set as L1+L2, wherein L2 is the natural number. Load inductance is reused when the multi-mode receiver radio frequency front-end low-noise amplifier works at high frequency and low frequency so that chip area is reduced and thus an objective of cost reduction is achieved. |
