Abstract :
A complete 12-bit voltage-out digital-to-analog converter that is fabricated in a 2-μm CMOS process and operates from a single 5-V supply is described. A sequence was developed to turn on current source segments in the two-dimensional array, which suppresses the INL (integral nonlinearity) due to the current source mismatch to ±1 LSB (least significant bit) and allows ±2 LSB of overall INL to be obtained without trimming the core. The guaranteed-monotonic output ranges from 0 to 2.56 V with a settling time of 3.0 μs
