12.1.1. Graphical Interpretation of I-V Characteristic

Try these first

1. 1.

   What does I-V stand for?

   Hint

   Think about the two electrical quantities involved.

2. 2.

   Define V_SD.

   Hint

   Consider where this voltage applies.

3. 3.

   What are the key components of the I-V characteristic?

   Hint

   Consider what two variables are being measured.

4. 4.

   Is V_SD equal to V_SD(sat) assumed in practical applications?

   • True
   • False

   Hint

   Think about practical assumptions in mathematics.

5. 5.

   An engineer measures the current through a device and notes a significant drop-off in performance at 3 volts. How would you graphically represent this and what could it imply?

   Hint

   Consider the implications of current drop relative to voltage increase.

6. 6.

   A silicon diode has an I-V curve that sharply increases after 0.7V. How would this inform your design decisions for a circuit using this diode?

   Hint

   Think about how certain components behave at their threshold voltages.
