1. What is Power Dissipation After Voltage Scaling?

Power Dissipation after Voltage Scaling is defined as how much power is dissipating after scaling down MOSFET by voltage scaling method in VLSI design. It's a crucial parameter in optimizing power consumption in integrated circuits.

2. How Does the Calculator Work?

The calculator uses the Power Dissipation After Voltage Scaling formula:

Where:

• \( P' \) — Power Dissipation after Voltage Scaling (Watt)
• \( S_f \) — Scaling Factor (unitless)
• \( P \) — Power Dissipation (Watt)

Explanation: The formula calculates the new power dissipation value after applying a scaling factor to the original power dissipation through voltage scaling techniques.

3. Importance of Power Dissipation Calculation

Details: Accurate power dissipation calculation is essential for thermal management, circuit reliability, and power optimization in VLSI design. Voltage scaling is a key technique for reducing power consumption in modern electronic devices.

4. Using the Calculator

Tips: Enter the scaling factor and original power dissipation values. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is voltage scaling in VLSI?
A: Voltage scaling is a power reduction technique where the supply voltage is reduced to decrease power consumption, though it may affect circuit performance.

Q2: How does scaling factor affect power dissipation?
A: The scaling factor directly multiplies the original power dissipation, showing the proportional change in power consumption after voltage scaling.
