Closed-loop systems utilize feedback to adjust their output based on the difference between the actual output and the desired output.

A depletion-mode FET is normally on, meaning it conducts current without any gate voltage applied, and requires a negative gate voltage to turn off.

The primary characteristic of a voltage follower configuration is that it provides unity gain.

A Zener diode is designed to operate in the reverse breakdown region, providing voltage regulation.

An open-loop control system operates without feedback, meaning it does not adjust its output based on the actual performance.

The primary difference is that N-channel MOSFETs use electrons as charge carriers, while P-channel MOSFETs use holes.

The primary disadvantage of an open-loop control system is that it cannot correct errors in output since it does not utilize feedback.

Natural gas power plants primarily use natural gas as fuel to generate electricity, often through combustion in gas turbines.

A DC-DC converter is used to change the voltage level of a DC signal, either stepping it up or stepping it down.
