- Q3. Scenario: 2 blocks 100 um apart. current of 8 mA flows with 10 ohms resistance. What should be the metal width for routing.(Need to show the complete calculation)
- Ans.
To determine the metal width for routing, calculate the resistance and use it to find the required width.
Calculate resistance using R = ρ * (L/A), where ρ is the resistivity of the metal, L is the distance between blocks, and A is the cross-sectional area of the metal.
Use Ohm's Law (V = I * R) to find the voltage drop across the metal.
Finally, use the voltage drop and current to determine the required metal width.
