Abstract
A receiver front end is provided with a low-noise amplifier (LNA), a linearity on demand (LOD) circuit, and a gain calibration device. The LOD circuit provides current to the LNA depending on linearity requirements. The gain calibration device monitors the amount of current provided by the LOD circuit to the LNA and provides signals to help compensate for variations in the LNA's gain due to the variations in the current supplied to the LNA by the LOD circuit. The compensation signals may be used to adjust the gain of a variable-gain amplifier, or may comprise compensation parameters usable by a digital signal processor, to compensate for the gain variations.
