As the reverse voltage is increased, the width of the depletion region increases as far as whole mobile carriers swept away from the intrinsic region. Reverse bias required by the PIN photodiode introduces a noise current which reduces signal to noise ratio, The reveres bias offers better performance for high dynamic range applications. In case a forward voltage is provided to the diode, the charge carriers from p and n region are injected into the intrinsic region. They can be manufactured to work forward or reverse, and with positive or negative voltage. From the above expression, it is clear that capacitance and distance are inversely proportional.

Avalanche photodiode     One type that is used for a variety of circuits is the PIN diode. The carriers diffuse across the junction because of the concentration gradient. This is so because applied forward potential reduces the depletion width. Hence, it allows the operation of the weak input signal. This article gives information about the difference between a PIN diode and APD to know more details about it. The intrinsic region offers very high resistivity of the order of 0.1 Ω-m. A PIN diode is almost similar to a normal PN junction diode however the only variation is the presence of intrinsic region. The PIN diode … The reverse bias required offers better performance for high bandwidth applications as the capacitance between the P and N regions as well as charge storage is small. Diodes     One of the key requirements for any photodetector is a sufficiently large area in which the light photons can be collected and converted. Sensitivity is very low in PIN photodiode. The figure below represents the symbol of PIN diode: Here, p region denotes the anode terminal and n region denotes the cathode terminal.

Schottky photodiode     The PIN diode is very good for RF switching, and the PIN structure is also very useful in photodiodes. RF connectors     The physical design of the photodiode needs to take account of this so that the light collection is optimised. PIN diode has many applications. Impatt Diode. The diode can detect all these forms of radiation. Photodiodes in general and in this case the PIN photodiode will respond differently to different light wavelengths. Valves / Tubes     Memory types     PIN Diodes PIN diodes are used as current-controlled resistors at RF and microwave frequencies, with resistances that can range from a fraction of an ohm when forward biased, or on, to greater than 10 … Photodiode structures     Both the PIN photodiode and PN photodiodes are widely used for a variety of photo-detection applications because of their characteristics. . Definition: A PIN diode is an advancement of normal PN junction diode. Inductors     So, as the forward voltage is increased, the greater number of charge carriers gets injected into the intrinsic region. The figure below represents the constructional overview of PIN diode: A PIN diode is formed by two methods, i.e., either by planar structure or mesa structure. Thyristor     You may know LED’s full form is Light Emitting Diode. Here P and N region serve as the two parallel plates of the capacitor.

This region is nothing but serves as the depletion region between P and N regions. The device functions as a capacitor in a reverse biased condition. The PIN photodiode provides additional sensitivity and performance over that of the basic PN junction photodiode. The PIN diode chip structure is shown in Figure A.1. It is generally the thickness of the top p type region or layer that is one of the key parameters in determining the response sensitivity. One of the key parameters within the design of the PIN photodiode is to enable the light to enter the intrinsic region. Due to this, the magnitude of the electric field also becomes large. PIN diode : PIN photodiode does not have a high-intensity electric field region. Supplemental material on PIN Diode … This … Full form … Thereby generating a PIN diode. Thus, with the increase in the distance the capacitance decreases. As this is relatively small, the sensitivity is not as great as that for some other forms of photo diode. Similarly, N+ region is also created on another side of the substrate. The capacitance vs. voltage of a typical PIN diode … MACOM’s PIN limiter diodes provide excellent broadband performance from 1 MHz to 20 GHz for receiver protector circuits. The PIN diode comprises three regions, namely the P-region (p-type semiconductor), I-region (intrinsic semiconductor) and N-region (n-type semiconductor). The basic PN photodiode is used in a number of instances. choosing the proper PIN diode-based product for a specific application is conspicuously absent. This is so because the doping level of N region is very much higher than I region. This chapter presents a general overview of PIN diode operating characteristics to form an adequate basis for the subsequent chapters on the various PIN diode functional circuits.
