Here is how the 'XOR' Delay equation looks like.

1.49 = 30 - (8.01 + (11 - 1) \cdot 2.05)

1.49ns = 30ns - (8.01ns + (11 - 1) \cdot 2.05ns)

1.49 = 30 - (8.01 + (11 - 1) \cdot 2.05)

'XOR' Delay Solution

Follow our step by step solution on how to calculate 'XOR' Delay?

FIRST Step Consider the formula

T xor = T ripple - (t pg + (N gates - 1) \cdot T ao)

Next Step Substitute values of Variables

∴

T xor = 30ns - (8.01ns + (11 - 1) \cdot 2.05ns)

Next Step Convert Units

∴

T xor = 3E-8s - (8E-9s + (11 - 1) \cdot 2.1E-9s)

Next Step Prepare to Evaluate

∴

T xor = 3E-8 - (8E-9 + (11 - 1) \cdot 2.1E-9)

Next Step Evaluate

∴

T xor = 1.49E-09s

LAST Step Convert to Output's Unit

∴

T xor = 1.49ns
