Hi, Kapylan,
I think the reference modulation looks like mismatch errors and vice versa, too.
Quote:In testing the reference modulation can look like mismatch errors and vice versa. Try to test at multiple clock rates to separate the two effects as mismatch is mostly a static error and reference modulation has a strong clock rate dependence.
But the amplifier settling error also looks like mismatch. So how to seperate the settling error and the reference modulation as both effects has a strong clock rate dependence?
Best regards,
