50MS/s current CMOS DAC is introduced.The DAC core is composed of an array of 31 thermometer-coded MSB current sources
15 thermometer-coded upper LSB (ULSB) current sources
and 5 binary-coded lower LSB (LLSB) current sources.Moreover the 5 MSB has a background self-trimming to meet high resolution.The new analog self-trimming technique introduced here does not need a replacement to replace the self-trimmed one.The circuit was fabricated in a 0.25μm CMOS technology.The die area is 3.54mm
2
.The measured results have shown that the circuit has more than 12 bit static resolution.
