In the base of the antenna is a small transistor to amplify the signal.

The tick refers to creating new methods of building smaller transistors.

Each year, the engineers find ways to create smaller transistors.

Mark answered by picking up the small transistor he had bought for Pranee.

Computers run faster with smaller transistors, because electrical signals take less time to travel from one place to another.

Making the processor out of smaller transistors means that it can run at higher clock speeds and produce less heat.

Its a new way to make smaller transistors that may or may not be feasible for large scale production.

Then engineers find innovative ways to create even smaller transistors and prove the journalist wrong.

But it's true that one day we'll hit the physical limits of how small traditional transistors can be.

That would be about one-twentieth the size of today's smallest transistors.
