Designers of inductors choose the wire size, number of turns, and core material to fit a given application, taking into consideration such factors as space available and the intended frequency range of operation. In general, inductors are used in analog circuits only when necessary, because for values above a few microhenries (μH, 10−6 H), these components tend to be bulky, PASSIVE DEVICES 13 heavy, and expensive. Also, because of the many turns of fine wire in the larger values, moisture or heat can cause differential stresses in the coil that break the wire, leading to failure.
The approach consists of first establishing what is called a DC operating point using the nonlinear device model and equations and then taking a derivative to find a linear equivalent value for the small‐signal model. This approach does not always work as neatly as it did for the hypothetical square‐law (quadratic) device in the example above, because usually nonlinear functions that characterize real devices have terms higher than second order in them. However, for all but the most nonlinear devices, taking derivatives in this way will produce a useful linear small‐signal model that can be used for AC signals that are not too large.
The silicon device substrate (the inert part of the silicon crystal that supports the device mechanically) is bonded to a mounting tab, typically made of plated copper, which extends beyond the plastic encapsulation that seals and insulates the device from the outside environment. The heat generated in the device flows through the mounting tab to the surface of the heat sink, which is usually made of a good thermal conductor such as aluminum. ) The dashed lines indicating heat flow go to the fins of the heat sink, which have a large surface area that allows both radiation and convection by air to carry away the heat transferred from the device.
