W: Proceedings of the 54th IEEE International Midwest Symposium on Circuits and Systems. - IEEE, 2011. -Streszczenie: A low power low voltage current mode 9-bit pipelined a/d converter and 8-bit self-calibrated d/a converter to interface a DSP system are presented in the paper. The a/d converter is built of 1.5 bit stages with digital error correction logic. The self-calibrated d/a converter is composed of M LSBs fine and N MSBs coarse current mode converters. The a/d and d/a converters were designed in 0.35μm technology, then fabricated to verify proposed concept. Performances of both converters are compared to performances of known converter structures. Low power consumption and small chip area are advantages of the proposed converters.
