HOW TO PLOT SINGLE GRAPH OF TWO EQUATION WHICH IS CONDITIONALLY SATISFIED

Vds=0:0.00001:.3; Vt=0.4; Vgs=0.6; Mn=398*10^-4; Cox=9.99*10^-10; p=2; k=Mn*Cox*p; Id1=k/2*(Vgs-Vt)^2; Id=k/2*(2*(Vgs-Vt).*Vds-Vds.^2); if Vds<Vgs-Vt Id;

else Id1; end plot(Vds,Id)

Answer 1

Hello,

Just define a variable which contains your result

if Vds<Vgs-Vt 
Result=Id;
else 
Result=Id1; 
end 
plot(Vds,Result)

[VBBV]

clear all; 
Vds=0:0.01:.3; Vt=0.4; Vgs=0.6; Mn=398*10^-4; Cox=9.99*10^-10; p=2; k=Mn*Cox*p; 
for kk = 1:length(Vds) 
if Vds(kk) < (Vgs-Vt)
  Idd(kk) =k/2*(2*(Vgs-Vt)*Vds(kk)-Vds(kk)^2);
else
Idd(kk) =k/2*(Vgs-Vt).^2;
end
end 
plot(Vds,Idd)
