Matching Circuit Technology Covering Wide Impedance Range (On-chip Antenna Impedance Tuner, AIT) The integrated impedance-matching circuit technology presented by Renesas at ISSCC 2015 enabled compact ...

The circuit is a microphone amplifier for use with low impedance (~200 ohm) microphones. It will work with stabilized voltages between 6-30VDC. If you don’t build the impedance adapter part with T1, ...

What is impedance matching? Applications of impedance matching. Impedance matching and design considerations. Impedance (Z) matching is an essential part of most RF circuit design. Regardless of what ...

The term “impedance matching” is rather straightforward. It’s simply defined as the process of making one impedance look like another. Frequently, it becomes necessary to match a load impedance to the ...

This mic preamp uses the low noise IC uA739. The circuit is an example of how a good preamplifier can be designed for dynamic microphones. The IC houses two identical integrated preamp circuits. The ...

Non-Foster circuit design offers a transformative approach to overcoming the intrinsic limitations of traditional passive matching networks. By utilising active elements to generate negative impedance ...

If you catch a grizzled old radio amateur propping up the bar in the small hours, you will probably receive the gravelly-voiced Wisdom of the Ancients on impedance matching, antenna tuners, and LC ...
