About Beta (Hfe), 'V_BE Voltage Drop', 'V_CE Voltage Drop' and Saturation'

  • What defines the 'V_BE Voltage Drop'? How does V_BE vary? Does the graph represent its behavior?

    • <excalidraw_not_loaded>

  • What defines what the 'Saturation Voltage' is?

    • It is defined based on the moment when the V_CE Voltage is zero, causing the Transistor to act as a Switch.

  • What defines the 'V_CE Voltage' drop?

  • How can I give "less or more "voltage drop"" to the Base -> Emitter? Is it changed by varying I_B?

  • What defines the value of Beta (Hfe)?

  • Why does the value of Beta (Hfe) change with temperature?

  • Need to do the Voltage variation, in the first case.

About Amplification

  • What are the possible constructions for 'current amplification'?

  • 'Common Emitter' vs 'Common Collector' vs 'Common Base (?)'?

  • First Order RC Filter; passive filter.

  • Operational Amplifier?

  • 'Common Emitter' and 'Class A' are the same thing? Or does one derive from the other?
