inl and dnl measurement
Hi All,
I had doubt in the measurement of INL & DNL.
1)
Is 1LSB = Iref/2^N
Here what should be the Iref value as LSB current
source has 20uA and MSB current source delivers
(20uA * 16). Here LSB = 4bits & MSB = 6bits.
Also should N be different or it should be 10
2)
For DNL measurement , it is 1LSB - [ Iout/2^N]. is this correct?
and how is the INL measurement made because
as per the definition it says draw a line joining
the first and last point.
Thanks
