  • On-die digital-to-analog conversion testing
    Patent number: 8314725
    Abstract: In one embodiment, an analog-to-digital conversion in an integrated circuit is evaluated by an on-die testing circuit. For example, the on-die test circuit 370 can characterize one or both of the linearity and monotonicity of the digital-to-analog conversion. The value of a conversion output for a digital input code may be compared to the value of a prior conversion output of a prior step to provide digital difference values for each step of a sweep of digital input codes. Digital difference values may be compared to one or more predetermined limits to provide one or more pass/fail tests on-board the die. Other embodiments are described and claimed.
