Question 1.
Describe the main advantage of the R-2R Ladder DAC.
Show hintHide hint
Think about how its design differs from the Binary-Weighted Resistor DAC.
Question 2.
What is the primary function of a DAC?
Show hintHide hint
Consider what the 'conversion' aspect entails.
3Question 3.
What is the main advantage of the Binary-Weighted Resistor DAC?
- Requires no precision resistors
- Limited scalability
- Fast conversion speed
Show hintHide hint
Consider what makes a DAC suitable for applications requiring quick responses.
4Question 4.
True or False: The R-2R Ladder DAC offers better speed than the Binary-Weighted DAC.
- True
- False
Show hintHide hint
Think about the core design differences.
Question 5.
Design a simple circuit diagram for a Binary-Weighted Resistor DAC and explain how it would convert a 4-bit binary signal to an analog output.
Show hintHide hint
Consider the bit significance for each resistor in the diagram.
Question 6.
Research and justify why the Current-Steering DAC is preferable in modern high-speed communication systems over others.
Show hintHide hint
Look into the performance metrics that are critical for communication systems.
