Method and system for a configurable low-noise amplifier with programmable band-selection filters

A method for communication, the method comprising:

• in a receiver comprising a low-noise amplifier (LNA) with a low pass filter operably coupled to a first input of the LNA and a high pass filter operably coupled to a second input terminal of the LNA, wherein the low pass filter and the high pass filter are also coupled to a signal source input:
• receiving signals in a pass band of the high pass filter and a pass band of the low pass filter;
• and
• configuring a wideband, high frequency, or low frequency mode of the LNA based on a signal received from a received signal strength indicator (RSSI).

A semiconductor device comprising:

• a receiver comprising a low-noise amplifier (LNA) integrated on a semiconductor die, the LNA comprising a low frequency mode, a high frequency mode, and a wideband mode, wherein:
• wideband mode comprises a low pass filter coupled to a first input of the LNA and a high pass filter coupled to a second input of the LNA;
• low frequency mode comprises the low frequency filter coupled to the first input of the LNA, the high pass filter shunted to ground utilizing a shunt resistor, and the second input of the LNA coupled to ground;
• high frequency mode comprises the high frequency filter coupled to the second input of the LNA, the low pass filter shunted to ground utilizing a shunt resistor, and the first input of the LNA coupled to ground;
• and
• the wideband, high frequency, or low frequency mode of the LNA is configured based on a signal received from a received signal strength indicator (RSSI).
