Understanding Integral Non-Linearity Errors
Abstract: To understand the effects of integral non-linearity errors, the most straightforward approach is to
analyze a simple sine wave and apply well-known trigonometric identities to a non-ideal, analog-to-digital
output transfer function, which contains an INL error.
With an ideal system, a single-tone sine wave with amplitude A and frequency fo,
X(t) = Asin(2π fot)
Sampling with an ADC with a period of T results i……
