Clipping level increases.
For example, if the clipping level was 2V before freezing, it will clip at a voltage greater than 2V when frozen.

Why clipper circuit is use?
A: SIGNAL could overshoot a value which can damage the input or output therefore a diode is used to clip these signals to a safe level
The only way to stop a 4 layers diode that is conducting is by?
To cause a Shockley diode to stop conducting, reduce the current going through it to a level below its low-current dropoutthreshold.
Difference between tunnel diode and PN junction diode?
there is difference between doping levels.In normal PN junction diode we add 1 impurity for 108 atoms where as in tunnel diode we add 1 impurity for 103 atoms.there is a probability that electrons may penetrate through barrier.So will not disappear in tunnel diode we get maximum current before barrier disappear where as we get maximum current after break down(there is no barrier) this effect lies within a certain voltage limit of 0.4V. When we consider the energy band structure in case of PN junction diode the fermi level lies inside the forbidden energy gap.In case of tunnel diode,the fermi level lies outside the forbidden energy band. In tunnel diode, there is a topic about negative resistance region where as we cannot discuss it in PN junction diode. ur friend, uma.
Do the ohmmeter test confirm the go-on-go test for the diode?
Yes, but only at a basic level. If the diode measures low resistance in one direction, high resistance in the other, you know that it is not short-circuited. But... 1. If it's a voltage-regulator/reference (Zener) diode, you do not know whether it has the correct breakdown voltage, 2. If diode leakage is important, you have not tested for leakage and the ohmmeter test does not do this reliably, 3. Your ohmmeter test voltage is probably no more than 9 volts, so you have not tested for high-voltage breakdown, and 4. If it's a rectifier (especially a high-current diode) you have not tested its forward voltage at full load current.
Why an approximate value required to turn on a npn silicon type transistor?
The base of a transistor is basically a diode wich follows an exponential curve at very low level it display an almost infinite inpedance but at hi lelvel any additional diode current will not increase its voltage drop therefore a nominal value is assigned of .6v to .7v

Why tunnel diode differ from the rectifier diode?
tunnel diodethe doping level of the tunnel diode is high when compared with the rectifier diodeit exhibits negative resistancerectifier diodethe doping level of rectifier diode is low when compared with the tunnel diode
What is the difference between clippers and clampers in electronics?
Clippers are diode, wave-shaping circuits. The output of clipping circuits looks like a portion of the input signal is clipped off, kind of like a limiter. A clipping circuit requires at least two basic components, a simple diode and a resistor. The output wave form can be clipped at different levels by interchanging the position of the diode and or resistor, and changing the voltage of the dc battery.
How can you change clipping level?
To change clipping in audio level you will have to do a few steps. First chick on the small icon in the lower left of the timeline that looks like a mountain, then click on the purple audio level line and drag it down to lower the level and if your wanting to increase it just drag it up.

What is positive peak clipping?
Friend, This is pretty difficult to explain without maths and a diagram, but I will give it a try. If you have seen a sinusoidal wave, which is like the "electrical component" of an electromagnetic wave. (Well, just imagine a wave), from zero it goes up to a certain level (called a crest) and to zero level and goes to a negative level (called trough). In some applications, like voltage regulators, you do not need the wave to the highest level. So what you do is to chop off the topmost part of the wave so that it meets your needs. The level of the clipping (chopping of the topmost part) is determined by the circuit. If you chop off the negative extreme (trough), it is called negative clipping.
Operation of led diode?
LED diode:when certain amount of voltage is applied to LED diode the electrons which are present in lower energy level jumps in to higher energy level after certain time the electrons in the higher energy level again jumps in to lower energy level .while jumping from higher energy level to lower energy level electrons emits energy in the form of light(visible or invisible)

What is the clip voltage?
When V(gs) is less than V(t). The minimum external energy which is provided to V(gs) in order to cross v(t) is know as clip voltage.
