Method and system for low noise amplifier (LNA) gain adjustment through narrowband received signal strength indicator (NRSSI)

摘要

Methods and systems for processing a plurality of signals are disclosed herein. Aspects of the method may comprise amplifying an input signal. The amplified input signal may be bandpass filtered. Amplification of the input signal may be adjusted based on only narrowband received signal strength indication of the bandpass filtered amplified input signal. The amplified input signal may be downconverted and a blocker signal may be bandpass filtered from the amplified input signal. Signal strength of a desired signal from the amplified input signal may be measured. The amplification of the input signal may be adjusted utilizing a triple well (TW) NMOS transistor. A control signal may be generated based on the narrowband received signal strength indication of the bandpass filtered amplified input signal. The amplification of the input signal may be adjusted based on at least one of the generated control signals.
