NMOS Triode Mode I–V Calculator

Calculate the drain current \(I_D\) for an NMOS transistor operating in the triode region.

* Ensure that \(V_{GS} > V_{TN}\) and \(V_{DS} < V_{GS} - V_{TN}\).

Step 1: Enter Transistor Parameters

Gate-to-Source Voltage, \(V_{GS}\) (V)

e.g., 2.5 V

Threshold Voltage, \(V_{TN}\) (V)

e.g., 1 V

Drain-to-Source Voltage, \(V_{DS}\) (V)

Must be less than \(V_{GS} – V_{TN}\) (e.g., 0.8 V)

Process Parameter, \(k’\) (A/V²)

e.g., 0.001 A/V²

\(W/L\) Ratio

Dimensionless (e.g., 10)
