Abstract
A method of tuning a receiver includes: providing a tunable Low Noise Amplifier (LNA) having a plurality of LNAs and a plurality of LC loads coupled to the plurality of LNAs; selecting a desired LNA and a LC load corresponding to the desired LNA; isolating the desired LNA from the selected LC load; generating a local oscillation (LO) signal; routing the LO signal to the output of the tunable LNA to generate a filtered LO signal; determining a first signal power level of the filtered LO signal; changing the capacitance in the selected LC load and determining a second signal power level of the filtered LO signal; comparing the first filtered signal power level to the second filtered signal power level; and according to the comparison result, determining whether or not to adjust the capacitance in the selected LC load.
