Hello , by definition DNK(K)=(V_out(K+1)-V_out(K)-Vlsb)/Vlsb
So for K=2
DNL(K)=(V_out(K+1)-V_out(K)-Vlsb)/Vlsb=((3/8)-(3/8)-(1/8))/(1/8)=-1 [LSB]
INK(K)=(V_out(K)-K*Vlsb)/Vlsb=(3/8)-2*(1/8))/(1/8)=1
In the place Where DNL is +1 i get -1 for some reason.I dont know how to interpet this large jump form DNL INL.
Howdo i methamichly derive the INL DNL of these K=2 case?
Thanks.
