As its name suggests, the depletion type MOSFET (DE-MOSFET) was developed to be used in either or both the depletion and enhancement modes. Construction of Depletion Type MOSFET: Figure 13.67 shows the construction of an N-channel DE-MOSFET. It consists of a lightly doped P-type sub...
Now for the theory, consider an NPN transistor, the BE junction isforward biasedand the CB junction isreverse biased. The width of the depletion region at the Junction CB is higher when compared with the depletion region of the Junction BE. When the BE junction is forward biased it decreases...
