Challenge Problems
Push your limits with challenges.
Question 1
A nanoscale MOSFET has a channel length reduction from 45nm to 20nm. Calculate how the threshold voltage would change using the DIBL equation: \( \Delta V_{th} \propto e^{-L/\lambda} \), assuming \( \lambda = 10nm \).
💡 Hint: Focus on how the ratio of L and \\( \\lambda \\) influences the value.
Question 2
Explain how the design of high-frequency amplifiers must change due to the effects of velocity saturation in nanoscale devices.
💡 Hint: Consider how linearity impacts amplifier design aspects such as bandwidth.
