The passive spiral inductor can be realized in different structure like square, circular, hexagonal, and octagonal with multiturns. The multi-turn inductors are used for higher inductance value design. The spiral Inductor is a two port multiturn planar inductor with multiple dielectric layers.
It is observed that the inductance of the square spiral inductor is more when compared to the rest of the spiral shapes. The magnitude of the inductance increases as the length of the inductor and area increases.
How-ever, the current model is sufficient for most practical inductors as the spiral sizes are usually limited by the chip area, which in turn prohibits the spiral line width to be greater than 20 m. IV. DESIGN METHODOLOGY
In radio frequency integrated circuits (RFIC) the spiral inductors dominates overall circuit performance and it is frequently used as a passive component in modern RFIC’s design technology. Here the passive planar spiral inductor is modeled and analysed. This example shows the analyses of different types of spiral inductors.
