Abstract: An improved delta sigma digital-to-analog converter in which the thermometer code, which is output from a thermometer code converter, is divided into P blocks for every Q bits. An arrangement of the blocks is shifted in rotation by a barrel shifter at a frequency fs. Along with this, an arrangement of bits within each block is shifted in rotation by a shift register at a frequency of Q times fs. The bits within the code thus obtained are provided to local DACs, each specified to correspond to each of the given bits. In this manner, it is possible to maintain a lower operating frequency while at the same time to reducing the distortion in the output caused by a change in shifting the data in rotation in the local DACs, which change occurs depending on bit levels of the data in a form of the thermometer code.
