Variables Used
DIBL Coefficient - DIBL coefficient in a cmos device is resprented typically on the order of 0.1.
Threshold Voltage DIBL - (Measured in Volt) - Threshold Voltage dibl is defined as the minimum voltage required by the source junction of the body potential, when source is at body potential.
Threshold Voltage - (Measured in Volt) - Threshold voltage of transistor is the minimum gate to source voltage required to create conducting path between the source and drain terminals.
Drain to Source Potential - (Measured in Volt) - Drain to source Potential is potential between drain and source.
STEP 1: Convert Input(s) to Base Unit
Threshold Voltage DIBL: 0.59 Volt --> 0.59 Volt No Conversion Required
Threshold Voltage: 0.3 Volt --> 0.3 Volt No Conversion Required
Drain to Source Potential: 1.45 Volt --> 1.45 Volt No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
η = (Vt0-Vt)/Vds --> (0.59-0.3)/1.45
Evaluating ... ...

What is the significance of Drain-Induced Barrier Lowering(DIBL)?

The drain voltage Vds creates an electric field that affects the threshold voltage. This drain-induced barrier lowering (DIBL) effect is especially pronounced in short-channel transistors. Drain-induced barrier lowering causes Ids to increase with Vds in saturation, in much the same way as channel length modulation does. This effect can be lumped into a smaller Early voltage VA. Again, this is a bane for analog design but insignificant for most digital circuits. More significantly, DIBL increases subthreshold leakage at high Vds.
