Varactor diodes, also known as "variable reactance diodes", are made by using the characteristic that the junction capacitance changes with the applied voltage when the pN junction is reverse biased. When the reverse bias voltage increases, the junction capacitance decreases, and conversely, when th Read More
Although traditional silicon diodes or germanium diodes can be used as rectifiers and switching elements in most electronic applications, but they do not have the functions such as electronic fine tuning, electronic attenuation, low-loss rectification, and reference voltage generation etc. In order Read More
