Abstract:
Methods and systems for a configurable low-noise amplifier with programmable band-selection filters may comprise a low-noise amplifier (LNA) with 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. The low pass filter and the high pass filter may also be coupled to a signal source input. Signals may be received in a pass band of the high pass filter and a pass band of the low pass filter. Input signals in the pass band of the one filter (but not signals in the pass band of the other filter) may be amplified by coupling the one input of the LNA to ground and coupling the other filter to ground utilizing a shunt resistor. The filters may be configurable and may each comprise at least one inductor and at least one capacitor.
