### Outline

• Determination VTH and unCox of ALD1106

• Simulate with

• ALD1106

• ALD1107

VTH~0.8 V

### ALD1106 NMOS

VTH~0.8 V

SQRT(unCoxW/L/2)=SQRT(0.04)/(3-0.8)2

unCoxW/L/2=0.33 mA/V2

### Measured Versus Calculation

Measured Values

Assume unCoxW/L/2=0.33 mA/V2

VTH=0.8 V

Sanity Check:

At 4.0 V, 0.33 mA/V2 (4-0.8)2 V2=3.37 mA

At 5.0V, 0.33 mA/V2 (4-0.8)2 V2=5.82 mA
