Engineers have crafted the world's highest-frequency circuit made with a common type of semiconductor transistor, a step that could slash the price of detectors useful in earlier cancer detection and ...

Ceramic resonators offer an attractive alternative to quartz crystals for stabilizing oscillation frequencies in many ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

A single-photon detector (SPD) is sensitive to incidence of individual quanta of light and has many applications in photonics, such as fluorescence measurements, laser ranging, optical time-domain ...
