Abstract
A semiconductor chip with a built-in-self-test circuit including a first analog-to-digital converter (ADC) configured to convert an analog input voltage signal received at its input into a digital output voltage signal that characterizes the first ADC; and a second ADC coupled to the input of the first ADC and configured to convert the analog input voltage signal received at its input to a digital feedback voltage signal, wherein the analog input voltage signal is generated based on the digital feedback signal.
