A MOSFET with Resistive Biasing as a Dependent Source Linear Circuit Opportunity

This video discusses a typical MOSFET linear amplifier that is biased using resistors, typical of a discrete circuit implementation. The transistor can be linearized to two voltage-controlled current sources and a resistor, transforming the original circuit into a linear circuit with dependent sources to solve. The intuition for both circuits, as well as one way to solve the circuit, is to transform the circuit part with voltage-controlled current sources into a single one-port linear block and proceed with the solution.

That's what I've been thinking for a while.
