How to write a program on ids vs vds characteristics of double gate mosfet for various lateral straggle value?

 FORMULA FOR Id 
Id=(2*W*un*Cox/Leff-ld+(Vds/Ec)) +(lambda* 2*W*Cox/(Leff-ld)^2)*[(Vgs-Vth)Vds-0.5Vds^2]
Lateral straggle

vary Vds by the intervals you want. By

W=324;
Cox=...
Define all the constants..
Vds=0:0.1:7%Vds Voltage value in Volts
Id=(2*W*un*Cox/Leff-ld+(Vds/Ec)) +(lambda* 2*W*Cox/(Leff-ld)^2)*((Vgs-Vth)*Vds-0.5*Vds^2)

plot(Vds,Id)

Glitches: use * for multiplication, Define the constants W, Un, Cox and L effective etc before the you define Vds.

SIR

After having defined all the constants i am not getting the output

W=324;
un=1;
Cox=3;
Leff=6;
ld=3;
Ec=1;
lambda=25*10^(-5);
Vgs=0.5;
vth=2.04;
DIBL=0.5;
Vth=vth-DIBL
Vds=0:0.1:7%Vds Voltage value in Volts
Id=(2*W*un*Cox/Leff-ld+(Vds/Ec)) +(lambda* 2*W*Cox/(Leff-ld)^2)*((Vgs-Vth)*Vds-0.5*Vds^2)
plot(Vds,Id)
end

Vds is a matrix of values from 0 to 7 in steps of 0.1. you cannot do 0.5*Vds^2 [in line 13]

instead do this...

Id=(2*W*un*Cox/Leff-ld+(Vds/Ec)) +(lambda* 2*W*Cox/(Leff-ld)^2)*((Vgs-Vth)*Vds-0.5*Vds.*Vds)

also see if this and this help:)
