Some operational amplifiers (op amps) have an inductive open-loop output impedance, which can be more complex to stabilize than op amps with resistive output impedances. One of the most common ...

The increasing use of voice-activated devices has put a spotlight on audio tests – making a case for open and closed loop testing, says Eric Hodges of Audio Precision. Classically, audio tests have ...

I had this long response all prepared, but then I remembered User Mode Linux. It's probably as close as you can get to what you are talking about, since you'll need something (a kernel already running ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...
