N2 - In this paper, a current-mode Built-In Self-Test (BIST) scheme is proposed for on-chip estimating static non-linearity errors in current-steering digital-to-analog converters (DACs). The proposed DAC BIST scheme is designed to verify a 10-bit segmented current-steering DAC, consist of a 5-bit coarse DAC and a 5-bit fine one. This proposed BIST scheme includes a current-mode sample-and-difference circuit to increase the sampling current accuracy and control a current-controlled oscillator (ICO). In addition, only 36 measurements are required by using the selected-code method rather than 1024 measurements for the conventionally-utilized all-code method. Compared to the conventionally-utilized all-code method, about 85-% reduction of test time can be achieved.
