Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

Will Kenton is an expert on the economy and investing laws and regulations. He previously held senior editorial roles at Investopedia and Kapitall Wire and holds a MA in Economics from The New School ...

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 term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

Every electrical component is the globe directly or indirectly needs the power to operate. To supply required power, a device known as a power supply is used. A power supply is an electrical unit ...

Normally, if you want to control the gain of an amplifier, you’ll use a variable resistor. You know, like a volume control. But what if you want to control the amplifier’s gain with a voltage?

Whether you’re aware of it or not, three-terminal voltage regulators automatically adjust power supply voltages in everything from audio consoles to distribution amplifiers to audio processing to STLs ...
