Heavy load capacitance can cause the output of a unity-gain follower—an operational amplifier with direct feedback to the inverting input (Fig 1)—to ring and oscillate. The LM110 follower, for example ...

You have voted. Unity-gain-stable op amps won in a landslide—they’re far more popular than decompensated op amps. What’s this all about? Unity-gain-stable op amps (let’s call them UGS) are stable in ...

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., ...

Michael Steffes challenges conventional approaches to Sallen Key Filter design. He says today's components and VFAs offer greater flexibility. This opinion piece links to more detailed explanations.

Linear Technology has introduced the LT6375, a unity-gain difference amplifier with integrated precision matched resistors, which precisely level shifts and buffers small difference signals while ...
