1. What is Multiplexer Delay?

Multiplexer Delay is the propagation delay of the multiplexer. It exhibits a minimum number of pmos and nmos, minimum delay, and minimum power dissipation in digital circuits.

2. How Does the Calculator Work?

The calculator uses the Multiplexer Delay formula:

\[ t_{mux} = \frac{T_{skip} - (t_{pg} + 2 \times (n - 1) \times T_{ao} - T_{xor})}{K - 1} \]

Where:

\( t_{mux} \) — Multiplexer Delay (s)
\( T_{skip} \) — Carry-Skip Adder Delay (s)
\( t_{pg} \) — Propagation Delay (s)
\( n \) — N-Input AND Gate
\( T_{ao} \) — AND-OR Gate Delay (s)
\( T_{xor} \) — XOR Delay (s)
\( K \) — K-Input AND Gate

Explanation: This formula calculates the multiplexer delay by considering various gate delays and input parameters in digital circuit design.

3. Importance of Multiplexer Delay Calculation

Details: Accurate multiplexer delay calculation is crucial for optimizing digital circuit performance, ensuring proper timing synchronization, and minimizing power consumption in complex electronic systems.

4. Using the Calculator

Tips: Enter all delay values in seconds. N-Input AND Gate and K-Input AND Gate must be positive integers (K must be greater than 1). All values must be valid and positive.
