Why does channel length modulation only occur in the saturation region?
As drain voltage is increased, the reverse bias across the drain-body junction also increases and thus the width of the junction should also increase which should deplete the channel length as well. ...

How temperature difference does not affect transistors in CPUs?
Recently I learned about semi-conductors and some devices.
Today I watched a video on youtube about a guy overclocking a cpu to 7.0 ghz, while cooling it with liquid nitrogen to -192 celsius degrees. ...

BJT Active mode - How does it work
I am finding it difficult to understand how exactly this works and would appreciate any help.
From my understanding:
The emitter base junction has to be in forward bias meaning that Vb is more ...

Why can current flow through the reverse biased base-collector junction (N-P junction) in a BJT with a forward biased base-emitter junction?
If the base-emitter junction of a BJT is forward biased, then current can flow through the reverse biased base-collector junction (N-P junction). This disagrees with my understanding of the PN ...

How is the PN junction formed?
I am confused about a couple of points:
When the electrons diffuse from N side to P side, and holes diffuse from P side to N side, negative charged region is formed at the junction in P type and ...

Potential drops in BJT in CE configuration?
In a simple p-n junction diode, there is a \$V_{eq}\$, the potential difference between the p-doped and the n-doped portion of the diode. When an external potential \$V\$ is applied in forward bias, ...
