Is there a model for determining the self resonant frequency of a flat spiral inductor? I can determine the inductance but the capacitance is escaping me.
Thanks for any help.
Thanks for any help.
The self-resonant frequency of a spiral inductor is the frequency at which the inductance and capacitance of the spiral cancel each other out, resulting in a high impedance. This is typically the highest frequency at which the inductor can function effectively.
The self-resonant frequency of a spiral inductor can be calculated using the formula f = 1/(2π√(LC)), where f is the frequency, L is the inductance, and C is the capacitance.
The self-resonant frequency of a spiral inductor is affected by several factors, including the number of turns, the size and shape of the spiral, and the materials used in its construction.
The self-resonant frequency of a spiral inductor is an important factor in its performance, as it determines the highest frequency at which the inductor can effectively filter or amplify a signal. Operating the inductor at frequencies above its self-resonant frequency can result in decreased performance and potential damage to the inductor.
Yes, the self-resonant frequency of a spiral inductor can be adjusted by changing the number of turns, the size and shape of the spiral, or the materials used in its construction. However, these changes may also affect other characteristics of the inductor, such as its inductance and resistance.
