2 cards from this section. Quick, good the night before a test.
What is the purpose of decoupling capacitors?
Think about the role of capacitors in stabilizing voltage.
Why are ferrite beads used in power supply circuits?
Consider the noise levels generated by digital circuits.
What is the main purpose of using dedicated analog regulators?
Think about how the components interact with each other.
True or False: Ferrite beads are used to filter out DC signals.
Remember what it means to isolate signals in a power supply context.
Design a mixed-signal circuit that minimizes noise interference. Include LDOs, decoupling capacitors, and ferrite beads. Specify their placements and values.
Think about the layout and how each component's positioning affects noise.
Analyze a scenario where an ADC's performance decreases due to power noise. Describe how to diagnose and implement noise reduction techniques.
Identify not only the symptoms but also the potential solutions based on the strategies discussed.
