摘要:
Aspects of a method and system for sharing low noise amplifier (LNA) circuitry in a single chip Bluetooth and wireless local area network (WLAN) system are disclosed. Aspects of the system may comprise a chip with integrated WLAN and Bluetooth radios. RF signals may be received via a single antenna coupled to a shared LNA integrated in chip. When WLAN signals are received they are communicated from the shared LNA to a subsequent amplification stage integrated within the WLAN radio. When Bluetooth signals are received they are communicated from the shared LNA to a subsequent amplification stage that comprises a transconductance amplifier integrated within the WLAN radio and an LNA load integrated within the Bluetooth radio. Gains in the LNAs, the transconductance amplifier, and/or the subsequent WLAN amplification stage may be dynamically adjusted. Outputs from the subsequent amplification stages may be communicated to mixers for further processing.
