An n+-polysilicon-gate p-channel MOSFET is made on an n-type substrate with Na=5x1016 cm3. The SiO2 thickness in 100Å, and the effective interface charge is Q=2x10'e/cm'. Calculate the flat-band voltage VFB, and the threshold voltage VT. Sketch the low frequency C-V and give numbers for the scales, such as the minimum and the maximum capacitance. Note: The SiO2 relative dielectric constant is 3.9.
Three-Phase Transformers
Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.
Transformer
Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
