Small-signal amplification and power amplification are dependent on  the application where they are going to be applied.  In most cases, the  frequency range of the signal is critical to its ability to carry the  information that is being transferred.   In this activity, we will explore the effects of the internal and  external capacitances on […]

  Basic Operation: JFETs (Junction Field-Effect Transistors) are kind of like spigots.  Using the image below, I'll explain my analogy of an N-Channel JFET. The Gate, formed by two p-type regions within the n-channel (which  are connected internally), acts as the valve body (handle, stem,  packing, etc.) This will restrict the flow of water- and […]

  I am going to talk about the basic operation MOSFET. MOSFET stands for metal oxide semiconductor field-effect  transistor. Like any conventional transistor, it is a type of transistor  with many applications in modern power electronics. Moreover, its  functioning is based on how electricity flows through it. It is  important to note that there are many […]

  As you said, these are  voltage-controlled devices. whereas BJTs are current controlled device.   Requiring no input control current is a major advantage of IGBTs. ". . . used in applications such as induction heating . . ." I have one of those induction-heated water pots for tea.  They heat scary fast and they have […]

 *You must show sufficient detail to support your work to  earn credit for your calculations. This can be hand-written work, typed  calculations, or excel formulas. To avoid round-off error, retain  at least six decimal places in all of your calculations.  Complete  all trigonometric calculations in radians.  k1andk2.PNG k3-yn1.PNG 4.5EngineeringAppliedExerciseRunge-Kutta.docx For more insight on where this approximation method […]

  In your own words compare the applications of different amplifier types and classes. Types of Amplifiers: a) Linear Amplifiers – These amplifiers are used to amplify weak  signals without distortion. They are commonly used in communication  systems, audio equipment, and instrumentation. b) Non-Linear Amplifiers – These amplifiers are used to amplify  signals with nonlinear […]
