ABSTRACT:
A digital-to-analog converter having a ladder resistor portion for generating a plurality of quantization signals of predetermined values based on reference signals of predetermined values and a quantization switch portion for selectively outputting one of the quantization signals in accordance with a digital input value. The ladder resistor portion is coupled to at least one resistor for generating a signal of a value which corresponds to a desired signal level of a signal to be added. A switch provided for supplying the signal of the value corresponding to the desired signal level to an output of the switch portion in response to a timing signal synchronized with the signal to be added.
