Abstract:
Apparatus and methods are also disclosed related to tuning a quality factor of an LC circuit. In some implementations, the LC circuit can be embodied in a low-noise amplifier (LNA). A quality factor adjustment circuit can increase and/or decrease conductance across the LC circuit. This can stabilize a parasitic resistance in parallel with the LC circuit. In this way, a gain of the LC circuit can be stabilized.
