ABSTRACT:
A data converting method is realized by a data-converting circuit including: a data combining circuit for outputting 1stthrough (2n−1)thintermediate data bits by combining data bits corresponding to “1”s in n-bit binary data corresponding to a decimal number; a thermometer code generating circuit for generating 1stthrough (2n−1)thbits of thermometer code data each activated as “1” when a corresponding intermediate data bit among the 1stthrough (2n−1)thintermediate data bits are activated, wherein each of the 1stthrough (2n−1)thbits of thermometer code data is additionally activated as “1” by the 1stthrough (2n−1)thintermediate data bits activated by binary data having a greater value than binary data activating the corresponding intermediate data bit; and a reset circuit for periodically resetting the 1stthrough (2n−1)thbits of thermometer code data to “0” in response to an external clock signal. A digital-to-analog converter incorporates the data-converting circuit.
