These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant circuit passes a specific wavelength (or more specifically range of wavelengths depending on ...

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 ...

An embedded process detector circuit which helps Integrated Circuit (IC) developers to address the problem of process variability on low-geometry CMOS designs. The process detector provides the means ...
