EXAMPLE pinch off voltage calculator:
INPUTS: Nd = 8E17 cm-3, a = 0.1 µm, Er = 13.10
OUTPUTS: Vp = 5.517 volts

MESFET Pinch off voltage formula or equation

Following MESFET pinch off voltage formula is used in this calculator.

MESFET pinch off voltage formula or equation

Vp = Pinch off voltage
q = charge in coulombs, 1.6 x 10-19
Nd = Electron Concentration in electrons per cm-3
a = channel height in meters
εs = εr x ε0
Here ε0 is permittivity of free space with value of 8.854 x 10-12 F/m, εs is permittivity of material in Farads/meter and εr is relative dielectric constant.
