What is bond wire inductance?

Bond wire is considered an extra inductance in circuit level simulation. It is also employed in hybrid MICs to make connections from the innermost section of the printed inductor [2] or connecting active devices.

Does thickness of wire affect inductance?

Inductance is affected by how much wire is in the coil and how close the turns are to each other. If you add more wire, by either making the diameter of the coil larger or adding more turns of wire, the inductance increases.

Do cables have inductance?

Yes. Every current carrying (or able to carry current) conductor has some measure of inductance. As you say, because when current flows, a magnetic field forms around the conductor. And when the magnetic field collapses, it can induce current in that conductor.

What is the self-inductance of a straight wire?

zero
As the self-inductance is given as proportional to the number of turns of the coils. Therefore in the case of a straight conductor, the self-inductance is always zero. Hence option (A) is the correct answer.

How the inductance of the single core cable can be calculated?

I have recently derived a formula for the inductance per unit length and capacitance per unit length of a single wire. They are respectively, L_0=R/c and C_0=1/Rc, where c is the speed of light.

What is bonding in RF design?

‘RF-bonding’ means achieving a low-impedance electrical connection at the highest frequency that must be controlled. For compliance with normal commercial/industrial EMC standards this is 1GHz, likely to become 2.7GHz or more in the near future.

What is a ball bonder?

A modern ball bonder is fully automatic and is essentially a self-sufficient industrial robot, complete with a vision system, sensors, and complex servo systems.

What does inductance depend on?

Inductance depends on the size and shape of a given conductor, the number of turns if it is a coil, and the kind of material near the conductor. A coil wound on a soft iron core far more effectively chokes the increase of a current than the same coil with an air core.

Which of the following factors will decrease inductance?

The greater the number of turns of wire in the coil, the greater the inductance. Fewer turns of wire in the coil results in lesser inductance. More coils of wires indicate a greater amount of magnetic field force for a given amount of coil current.

Does all wire have inductance?

A straight wire carrying a current does indeed store energy in a magnetic field so it does have an inductance. For example see Derivation of self-inductance of a long wire. However the inductance of a straight wire is very small.

Why does wire have inductance?

Straight wires and coils have an inductance. Normally coils are used for inductors because the linking of the magnetic field between the different turns of the coil increases the inductance and enables the wire to be contained within a smaller volume.
