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

A system for processing a plurality of signals, comprising:

• a single chip comprising:
• a low noise amplifier (LNA) that amplifies an input signal;
• a downconversion mixer that generates a wideband signal from said amplified input signal;
• a bandpass filter that bandpass filters said generated wideband signal to generate a narrowband signal;
• and
• at least one received signal strength indicator block that measures signal strength of at least one desired signal from said amplified input signal to generate a narrowband received signal strength indication (NRSSI) of said generated narrowband signal, and/or a wideband received signal strength indication (WRSSI) of said generated wideband signal,
• wherein said at least one received signal strength indicator block generates at least one control signal based on said narrowband received signal strength indication and/or said wideband received signal strength indication;
• wherein said LNA adjusts amplification of said input signal based on said narrowband received signal strength indication, and/or said wideband received signal strength indication, and wherein said LNA adjustment of said amplification of said input signal comprises utilizing an on-chip triple well (TW) N-channel Metal Oxide Semiconductor (NMOS) transistor;
• and
• wherein said at least one control signal corresponds to a powering state of said on-chip TW NMOS transistor.
