4.5.1. Signal Feeding and Resistance Considerations

Try these first

1. 1.

   What is the cut-in voltage for a silicon diode?

   Hint

   Remember standard silicon diode characteristics.

2. 2.

   Describe what happens when the input voltage is below the cut-in voltage.

   Hint

   Think about the diode's operation state.

3. 3.

   What is the typical cut-in voltage for silicon diodes?

   • 0.1 V
   • 0.6-0.7 V
   • 1.2 V

   Hint

   Consider standard properties of silicon.

4. 4.

   True or False: The diode is ON when the input voltage is below the cut-in voltage.

   • True
   • False

   Hint

   Visualize the diode's operational states.

5. 5.

   Given a signal with an amplitude of 2V and a DC bias of 3V applied to a diode-resistor combination, determine the behavior of the output signal.

   Hint

   Focus on the combination of DC and AC aspects.

6. 6.

   A circuit has a forward bias of 0.7V and an R_on of 20 ohms. If the input voltage increases to 5V with a max AC variation of 0.5V, what is the output voltage considering current flow?

   Hint

   Using Ohm's Law will help simplify this.
