Calculate Channel Length Modulation Coefficient





Formula

The formula to calculate the channel length modulation coefficient (λ) is:

\[ \lambda = \frac{\Delta I_D}{I_D \cdot \Delta V_{DS}} \]

Where:

Definition

Example

Let's say the change in drain current (ΔI_D) is 0.01 A, the drain current (I_D) is 0.1 A, and the change in drain-source voltage (ΔV_DS) is 5 V. Using the formula:

\[ \lambda = \frac{0.01}{0.1 \cdot 5} \]

We get:

\[ \lambda = 0.002 \]

So, the channel length modulation coefficient is 0.002.
