How Does a MOSFET Really Work? | Channel Creation (Step-By-Step)

Описание: How Does a MOSFET Really Work? | Channel Creation (Step-By-Step) | VLSI Design EP6

🤔 Ever wondered what happens inside a MOSFET when you apply voltage? In this VLSI Design lecture, we break down the MOSFET working principle **step-by-step**, focusing on the magical moment of **channel creation**. Perfect for students, engineers, and curious minds!

🔬 *What You'll Learn:*
✔️ Basic MOSFET structure (Source, Drain, Gate, Body)
✔️ Role of gate voltage (Vgs) in forming the depletion region
✔️ How the inversion layer is created step-by-step
✔️ Understanding Threshold Voltage (Vth) – the ON/OFF switch
✔️ Visualizing channel formation with clear animations/diagrams
✔️ MOSFET as an electronic switch – practical insight

📌 *This Lecture is For:*
• Electronics & Communication Engineering Students
• VLSI, Semiconductor, and Chip Design Enthusiasts
• GATE, ESE, PSU, and University Exam Aspirants
• Professionals looking to refresh fundamentals
