Proteus Tutorial – Light Emitting Diode (LED) and Bar Graph Display

  How to work with Light Emitting Diode (LED) in Proteus In this post we will be learning on how to use the “Light Emitting Diode (LED)” component in Proteus simulation software. In case you have not got on through the basics of Proteus, here is the link – Proteus [...]

Diodes. Amplitude Modulation Diode Detection

Diodes are the fourth basic discrete component listed in These and transistors are both nonlinear devices. Nonlinear devices are necessary for electrical communications. There are four types of diodes used in the NorCal 40A: 1. Silicon – used for rectification, electronic switching. 2. Schottky – used [...]

Limiting and Clamping Diode Circuits

Voltage Doubler. Special Diode Types . We’ll finish up our discussion of diodes in this lecture by consider a few more applications. We’ll discuss limiting and clamping circuits for diodes as well as voltage doubling circuits. Voltage Limiting Circuits These types of circuits are used to “cap” [...]

Explain double hairier tunneling and the resonant tunnellillg diode.

Ans. In the case of resonant tunnelling two barriers separated by a small distance forming a potential well as shown in fig. 2.24. Fig. 2.24 Double Barrier System Forming a Potential Well We consider that the barriers are sufficiently thin to allow tunnelling and that the well [...]
