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 ...

The creative new approach could lead to more energy-efficient machine-learning hardware. On a table in his lab at the University of Pennsylvania, physicist Sam Dillavou has connected an array of ...

In most operational amplifier (op amp) circuits, the resistor tolerance and resistor temperature coefficient determine the gain accuracy and gain temperature drift (Figure 1 shows a typical circuit).
