Abstract
An interleaved DAC configured to generate a set of second digital inputs responsive to a set of first digital inputs. Each second digital input is obtained by subtracting the other second digital inputs in the set from the corresponding first digital input. Two consecutive first digital inputs are shifted by a phase of T=1/f. The second digital inputs are supplied to a set of sub-DACs arrange in parallel. Each sub-DAC operates at a frequency of f/R, and drives an analog output responsive to each second digital input for a duration of R×T. Clock signals used by two sub-DACs for converting two consecutive second digital inputs are offset by a phase of T. In each interval of T, summation of the analog signals output from the set of sub-DACs produces an analog value of a single first digital input, thereby achieving a data conversion speed of f.
