How do you increase the q factor of an inductor?

To increase the Q factor of an inductor, you can reduce its series resistance (R) by using high-conductivity materials for the wire and optimizing the winding technique to minimize losses. Additionally, increasing the inductance (L) by using a core material with high permeability or increasing the number of turns can also enhance the Q factor. Lastly, minimizing the parasitic capacitance through careful design can help maintain a higher Q at resonant frequencies.
