studyelectronics Sets of rules to simplify the given logic Complement \(A\) complement \(= \overline{A}\) or \(A’\) \((A’)’ = A\) AND \(\begin{aligned} A.A&=A \\ A.0&=0 \\ A.1&=A \\ A.A’&=0 \end{aligned}\) OR \(\begin{aligned} A+A&=A \\ A+0&=A \\ A+1&=1 \\ A+A’&=1 \end{aligned}\) Distributive Law \(\begin{aligned} A.(B+C) &= A.B+A.C \\ A+(B.C) &= (A+B).(A+C) \end{aligned}\) from there, we can get \(\begin{aligned} … Read more
A bipolar junction transistor (BJT) is a three-terminal semiconductor device used for amplifying and switching electronic signals. output current, voltage, and/or power are controlled by its input current. A BJT consists of two p–n junctions combined together and uses both electrons and holes as charge carriers, which is where its “bipolar” name comes from. The … Read more
FET is voltage controlled device.
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is one of the most important building blocks of modern electronic circuits. A transistor controls the flow of current — it can allow or block current depending on the input signal applied to it. In simple words, it … Read more
THe semiconductor diode is formed by simply bringing n and p type materials together (cnstracted from same base Ge or Si). Also called as pn junction diode or crystal diode Diffusion Diffusion current Depletion region/ deplition layer/ space charge region Drift current Under steady state, diffusion current = Drift current. Nett current = 0 for … Read more
Semiconductor has negative temperater cofficient, means if temperature increase, resistance decrease. in case of conductor the temperature cofficient is positive.

A simple semiconductor, in it pure, undopped form is called intrinsic semiconductor. The impurity is very low in a intrinsic semiconductor, about one in 100 million parts. In the intresic semiconducter number of free electrons equals the number of holes. Crystal Structure of Intrinsic Semiconductor
