Varactor Diode Short Note
The varactor diode acts like a variable capacitor under reverse bias. This means that initial changes in reverse voltage give a much greater change in capacitance than those at higher voltages. Lecture 2 Semiconductor Diodes Ppt Download Types Of Diodes Applications Functions Types Of Diodes Types Of Diode In Mobile Phone And Their Function Zener In view of the fact that the varactor diode is a semiconductor diode many parameters are the same as those of other diodes. Varactor diode short note . The varactor diode has a non linear capacitance curve the capacitance of the varactor diode is inversely proportional to the square root of the voltage across it. The varactor diode symbol consists of the capacitor symbol at one end of the diode that represents the variable capacitor characteristics of the varactor diodes. The reflection phase shift for different ele...
