Abstract
Various embodiments are disclosed relating to Q-enhancement cells. According to an example embodiment, a circuit may include an inductor with a quality factor (Q), and a Q-enhancement cell coupled to the inductor. The Q-enhancement cell may include a current source having a variable bias current slope. Stability may, for example, be improved by providing a variable or programmable bias current slope for the Q-enhancement cell. In another example embodiment, a Q-enhancement cell may be used to compensate for Q degradation due to one or more switched capacitors in a circuit. The switched capacitors may be used, for example, for channel or frequency selection for the circuit. In another example embodiment, a Q-enhancement cell may be used to compensate for Q degradation caused by a transmission line.
