We have already studied what is DC biasing in transistors, now let’s move ahead and learn how an emitter resistor can be used for improving the stability of a BJT DC bias network. Applying Emitter Stabilized Bias Circuit The inclusion of the emitter resistor to the dc bias of the BJT delivers superior stability, meaning, … Read moreEmitter-Stabilized BJT Bias Circuit
So far we have been studying BJT analysis dependent on the level of β over their corresponding operating points (Q-point). In this discussion we will check out how a given circuit conditions can help in determining the possible range of operating points or Q-points and in establishing the actual Q-point. What is Load Line Analysis … Read moreLoad-Line Analysis in BJT Circuits
In this article we try to understand Ohm’s Law and Kirchhoff’s Law through standard engineering formulas and explanations, and by applying linear first-order differential equation to solve example problem sets. What’s an Electric Circuit A simplest electric circuit is generally in the form of a series circuit having an energy source or electromotive force input, … Read moreUnderstanding Ohm’s Law/Kirchhoff’s Law using Linear First-Order Differential Equations
In the previous post we learned BJT biasing, in this article we will learn what is transistor or BJT saturation and how to determine the value quickly through formulas and practical evaluations. What is Transistor Saturation The term saturation refers to any system where the specification levels have attained the maximum value. We can take the example … Read moreWhat is Transistor Saturation
The working of a Bipolar transistor or BJTs at DC levels is governed by several factors, that includes a range of operating points over the characteristics of the devices. Under the section 4.2 explained in this article we will check the details regarding this range of operating points for BJT amplifiers. Once the specified DC … Read moreDC Biasing in Transistors – BJTs
