Which limitation arises when optimizing gallium arsenide transistor speed?

💡 Explanation

Velocity saturation limits transistor gain because above a critical electric field, the electron's drift velocity plateaus due to increased scattering, therefore transistor performance peaks there, rather than continuing to increase linearly as charge flow increases.
