inductance

In physics, phenomenon in which a changing current in a circuit builds up a magnetic field which induces an electromotive force either in the same circuit and opposing the current (self-inductance) or in another circuit (mutual inductance). The SI unit of inductance is the henry (symbol H).

A component designed to introduce inductance into a circuit is called an inductor (sometimes inductance) and is usually in the form of a coil of wire. The energy stored in the magnetic field of the coil is proportional to its inductance and the current flowing through it. See electromagnetic induction.

The transistor pattern and circuit-block layout are optimized to reduce parasitic capacitances and inductances that would otherwise degrade high-frequency characteristics.
This approach offers high-frequency, high-efficiency performance, allowing the design engineer to fully optimize both electrical and PCB designs since parasitic inductances and resistances are almost fully eliminated.
