Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

Sometimes it is useful to have a variable resistor that can be controlled via a microcontroller, even if the adjustment resolution is not very fine. Often, as few as 16 steps are adequate (e.g., for ...

Abstract: The floating node voltage-controlled linear variable resistor circuit is a versatile building block in several analog signal processes such as telecommunications and electronics. Floating ...

Abstract: A linear voltage controlled variable resistor in partially depleted silicon-on-insulator (PD-SOI) technology is presented. Stacked FET structure is utilized for the variable resistor ...

If you need a potentiometer for a project, chances are pretty good that you’re not going to pick up a pencil and draw one. Then again, if you’re teaching someone how a variable resistor works, that ...

Adjusting the volume dial on a sound system, sensing your finger position on a touch screen, and knowing when someone’s in the car are just a few examples of where you encounter variable resistors in ...

Moving the position of the slider on this resistor, changes the length of wire in the circuit which changes the resistance. A variable resistor is used in some dimmer switches and volume controls. As ...

Resistor with simple electric circuit scheme. Physical test for education in schools at physics lesson. Rheostat is an electrical instrument used to control a current by varying the resistance.

Designers of instruments or control systems often find that component performance limits overall equipment performance in areas such as stability, frequency response, noise, and ESD. This is ...
