PMOS Saturation I–V & Transconductance Calculator

Calculate the drain current $I_{D}$ and transconductance $g_{m}$ for a PMOS in saturation mode.

* Ensure that $V_{S G} > V_{T P}$ . (Enter voltages as positive numbers)

Step 1: Enter PMOS Parameters

Source-to-Gate Voltage,

V_{S G}

(V)

e.g., 3.0 V

Threshold Voltage,

V_{T P}

(V)

e.g., 1.0 V (absolute value)

Process Parameter,

k_{p}

(A/V²)

e.g., 0.001 A/V²

W / L

Ratio

Dimensionless (e.g., 10)
