    Describes a monolithic 14-bit DAC which uses a new compensation technique for the DAC linearity, the `self-compensation technique', originated through a new concept. Since this technique automatically compensates for linearity error in the DAC by referring to a ramp function with about 17-bit linearity, a high precision DAC can be produced in monolithic form without the trimming of analog componen...
