The circuit diagram is mentioned. other hand, application of reverse bias to the photo-diode causes the dark current (Id) to increase, leaving a voltage of Id × RL when the light is interrupted, and this point should be noted in designing the circuit. The backward diode or the back diode is a P-N junction diode, whose operation is similar to that of tunnel diode and Zener diode. Pin diode is used as RF switch or variable resistor as they produce fewer distortions than a normal diode. Quad PIN diode attenuator Rev. Application of PIN Diode. Materials and Methods The PIN Diode The BARC developed PIN diode is similar to a p-n junc-tion diode but it is fabricated on a high resistivity silicon substrate. The low forward resistance of the intrinsic region decreases with increasing current. PIN Diode Modeling The PIN diode is a current controlled resistor at radio and microwave frequencies. The p-type and n-type regions are typically heavily doped because they are used for ohmic contacts.. Pin diodes are used for a number of applications. A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other.
