A back-to-back varactor diode between the split of the resonator controls the odd-mode resonant frequency, and a single varactor diode is placed at the center of the resonator to adjust the even-mode ...

The proposed tunable structure, which is composed of inductors and varactor diode arrays, offers a continuous tuning ... Notably, the LNA is unconditional stable across the entire frequency range. The ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can do that with ...

Numerous optical technologies are used in displays, including organic light-emitting diodes and inorganic light-emitting diodes, liquid crystals and fluorescent materials. Important considerations ...
