4.1. Analog Electronic Circuits

Try these first

1. 1.

   What defines a diode's non-linear behavior?

   Hint

   Think about how current behaves in relation to voltage.

2. 2.

   What is the reverse saturation current?

   Hint

   Consider the small current level when the diode is off.

3. 3.

   What describes a diode's current-voltage relationship?

   • Linear
   • Exponential
   • Constant

   Hint

   Recall the I-V characteristic curve.

4. 4.

   True or False: If V_in is less than the cut-in voltage, the output voltage will equal V_in.

   • True
   • False

   Hint

   Think about the diode's conducting state.

5. 5.

   If a circuit contains a diode with a cut-in voltage of 0.7V and a resistor of 1kΩ. Calculate the current flowing when the input voltage is 1.5V.

   Hint

   Remember to apply voltage drop across the diode when calculating.

6. 6.

   Analyze how a diode in series with a capacitor behaves if the frequency of the AC signal is increased significantly.

   Hint

   Focus on the reactance of the capacitor at high frequencies.
