A bipolar transistor or a BJT is a 3 terminal semiconductor device which is able to amplify or switch small signal input voltages and currents to significantly larger output signal […]
Voltage-Divider Bias in BJT Circuits – More Stability without beta Factor
Biasing the terminals of a bipolar transistor using a calculated resistive divider network for ensuring an optimal performance and switching response is called voltage divider biasing. In the previous bias […]
Emitter-Stabilized BJT Bias Circuit
A configuration in which a bipolar junction transistor or a BJT is reinforced with an emitter resistor for enhancing its stability with regards to changing ambient temperatures, is called an […]
Load-Line Analysis in BJT Circuits
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 […]
Ohm’s Law/Kirchhoff’s Law using Linear First-Order Differential Equations
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 is Transistor Saturation
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. […]
