P N Junction Theory and diodes (Part I) - GATE Problems 1. In a junction diode (a) the depletion capacitance increases with increase in the reverse bias (b) the depletion capacitance decreases with increase in the reverse bias (c) the depletion capacitance increases with increase in the forward bias

P517/617 Lec 5, P7 Transistors • Transistors are the heart of modern electronics (replaced vacuum tubes) voltage and current amplifier circuits high frequency switching (computers) impedance matching low power small size, can pack thousands of transistors in mm2 • In this class we will only consider bipolar transistors. P N Junction Theory and diodes (Part II) - GATE Problems 1. The diffusion capacitance of a P - N junction (a) Decreases with increasing current and increasing temperature (b) Decreases with decreasing current and increasing temperature (c) Increases with increasing current and increasing temperature P-N Junction One of the crucial keys to solid state electronics is the nature of the P-N junction. When p-type and n-type materials are placed in contact with each other, the junction behaves very differently than either type of material alone. Specifically, current will flow readily in one direction (forward biased) but not in the other (reverse biased), creating the basic diode. Due to this characteristic, the diode finds number of applications as given below: Rectification; The conversion of alternating current into direct current is known as rectification. A p-n junction diode allows electric current when it is forward biased and blocks electric current when it is reverse biased. This article provides a more detailed explanation of p-n diode behavior than that found in the articles p-n junction or diode.. A p-n diode is a type of semiconductor diode based upon the p-n junction.The diode conducts current in only one direction, and it is made by joining a p-type semiconducting layer to an n-type semiconducting layer.
