Question
**Problem Statement:**

5.33 An NMOS transistor is fabricated in a 0.18-μm process having \( k'_n = 400 \, \mu A/V^2 \) and \( V'_A = 5 \, V/μm \) of channel length. 

Given:
- \( L = 0.54 \, μm \)
- \( W = 5.4 \, μm \)

Tasks:
1. Find \( V_A \) and \( λ \). 
2. Determine the value of \( i_D \) when the device operates with an overdrive voltage of 0.25 V and \( v_{DS} = 1 \, V \).
3. Find the value of \( r_o \) at this operating point. 
4. Calculate the change in \( i_D \) if \( v_{DS} \) is increased by 0.5 V.
