EQUIVALENT CIRCUIT

The inductor’s spiral trace presents a substantial amount of series resistance, and the close spacing of the spiral turns presents

measurable amounts of stray capacitance that interact with the inductive characteristics.

A useful tool commonly used to model the behavior of electronic components at high frequency is the equivalent circuit model.

While the equivalent circuit model accurately predicts the reactive part of the total impedance, it fails to determine the real part

of the response at high frequency. This is due to the fact that the model does not include skin and proximity effects that

significantly increase the real part of the impedance as the frequency rises.

LAYOUT CONSIDERATIONS

The RF spiral inductor is electrically connected to the circuit by wire bonds. All wire bonds add parasitic inductance and

resistance, as shown in Figure 1.

It is important to note that setup variations might affect the performance of the component. Special care must be given to

minimize these effects by careful design of the component host circuit board. The following aspects should be considered:

• Bond wire length should be minimized. The bond wire added inductance can be roughly estimated at 0.75 nH per mm of

1.25 mil diameter gold wire.

• Any ground plane directly under the component will increase the parasitic shunt capacitance. This will cause self-resonance

at lower frequencies.

• The epoxy used to attach the component is the limiting factor in power handling. For applications that require high power

handling it is recommended to use high temperature epoxy and to ensure adequate heat sinking.
