Silicon is actually a semiconductor material which usually do not conduct under normal conditions. Conduction can take place under special conditions. A transistor is fabricated by adding purities in the substrate such that one part of the layer has excess of either positive or negative charges. Negatively charged region is called the n-type region and positively charged region is named as p-type region. The structure of NMOS transistor is shown in the figure below.
In CMOS circuits, pull up device is replaced with a pull up network (PUN) which is designed using PMOS transistor. This arrangement should be such that the circuits implemented by PDN and PUN should be the complement of each other.
Explain working of Programmable Logic Controller (PLC). Programmable logic controller is present in almost every industry. As the name suggests, we control digital and analog logics by embedding a program on hardware or module of the system.
