10. Revisiting MOSFET - Part A
The chapter delves into the fundamental concepts of MOSFET devices, including their basic structure, operating principles, and the I-V characteristics of n-MOSFETs. It contrasts the advantages of MOSFETs over BJTs, particularly in integrated systems that combine analog and digital interfaces. The discussion proceeds to highlight the importance of understanding these devices for practical applications within analog electronics.

What we have learnt
- The basic structure of a MOSFET includes a gate, body, source, and drain.
- The operating principle of n-MOSFETs involves voltage modulation to create a conductive channel between source and drain.
- MOSFET technology is crucial for integrating analog and digital systems on a single chip.
Key Concepts
- -- MOSFET
- A metal-oxide-semiconductor field-effect transistor that uses an electric field to control the flow of current.
- -- IV Characteristic
- The relationship between the current flowing through the MOSFET and the voltage applied across it, showing how current varies with gate voltage.
- -- Threshold Voltage (Vth)
- The minimum gate-to-source voltage that is needed to create a conductive channel.
