A cascode configuration reduces reference modulation error in a 4-20 mA current mirror, improving active impedance by orders of magnitude.

When shopping for loudspeakers or headphones, most consumers don’t even look at the impedance of the products they are considering. Do they need to? What is Impedance? Glad you asked. Most consumers ...

Have you ever wondered what makes a loudspeaker “difficult to drive”? Do you wonder what’s so special about an amplifier that is stable into a 4 ohm load? If these are the kinds of questions that ...

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...
