If you use a gyrator and a capacitor to make a virtual inductor, that inductor won’t magnetically couple to another inductor, real or simulated. There’s no magnetic field to do so.

There’s one component which used to be ubiquitous in every experimenter’s junk box, but nowadays unless you happen to be a radio amateur the chances are you may not have seen one in a l… ...

Here is a simple, compact circuit for isolating a low power –48V output. The gyrator circuit allows AC signals to ride on the DC output voltage, adding audio signaling capability for communications ...

C2 is a dc blocking capacitor. The UUT includes a current sink, I 1 , and a termination network, R5 and C3. This setup allows designers to perform some typical ac tests, such as return loss, total ...

Electronically-variable capacitors, whether used for T&M or in an end circuit, usually have a maximum capacitance of a few hundred picofarads, and a limited adjustment range. This Design Idea ...

The capacitor Q is in the 20 to 35 range depending on frequency with a voltage capability up to 30 V peak RF. Inputting a 5-bit word changes the capacitance. Switching time is 12 µs with a 10-µs ...
