13. Revisiting MOSFET (Contd.)
The chapter provides an in-depth exploration of the graphical interpretation of the I-V characteristics of MOSFETs, particularly focusing on both n-MOSFET and p-MOSFET devices. Key operational regions such as triode and saturation are discussed, highlighting their dependency on voltage thresholds. Numerical examples are included to illustrate the practical applications and calculations associated with these devices in electronic circuits.

What we have learnt
- The graphical representation of the I-V characteristics for both n-MOSFET and p-MOSFET.
- Operational regions of MOSFETs: triode region, saturation region, and cutoff region.
- The significance of parameter adjustments such as transconductance and the effects of pinch-off conditions.
Key Concepts
- -- Triode Region
- The operational region where the MOSFET behaves like a resistor and the current is linearly related to the gate-source voltage.
- -- Saturation Region
- An operational state of the MOSFET where the current is almost constant regardless of the drain-source voltage, dominated by gate-source voltage.
- -- Threshold Voltage (Vth)
- The minimum gate-source voltage that is required to create a conducting path between the source and drain terminals of the MOSFET.
- -- Transconductance Parameter (K)
- The parameter that defines the performance characteristics of the MOSFET in terms of its current output in relation to its gate-source voltage.
