In this paper, an google pixel 7 freedom on-chip self-calibrated 8-bit R-2R digital-to-analog converter (DAC) based on digitally compensated input offset of the operational amplifier (OPAMP) is presented.To improve the overall DAC performance, a digital offset cancellation method was used to compensate deviations in the input offset voltage of the
Research on visual expertise has progressed significantly due to the availability of eye tracking tools.However, attempts to bring together research on expertise and eye tracking methodology provoke several challenges, because visual information processes should be studied in authentic and domain-specific environments.Among the barriers to designin
