This letter proposes an improved dc-single tone approximation model to calculate the RF-dc conversion efficiency, voltage sensitivity, and input impedance of rectification circuits comprising n diodes ...

The remote variable resistor functions as a voltage-controlled resistor whose resistance changes based on an applied voltage.

In this brief, we designed, constructed, and analyzed a frequency-tunable metamaterial resonator. The proposed design consists of an S-shaped resonator, a ground frame, and a feeding transmission line ...

In DC voltage applications, the RC snubber network is typically wired across the relay contacts, whereas in standard AC ...
