The diode connected MOSFET — clearly explained

This video explains the diode-connected MOSFET and walks through a complete small-signal gain analysis step by step. Using a diode-connected MOSFET biased with a resistor 𝑅_𝐷 to generate the DC current 𝐼_𝐷, we derive the voltage gain using the key amplifier relationship: Av​=−Gm​Rout​ This video also explains why diode-connected MOSFETs are important in analog IC design, including their use as a precision nonlinear resistor, in current mirror biasing, and as an active load that improves robustness against temperature variation and process drift. Perfect for students studying MOSFET small-signal models, analog amplifier design, current mirrors, and CMOS integrated circuits.
