Abstract:
A digital-to-analog conversion apparatus has a first digital-to-analog converter, at least one second digital-to-analog converter, and a combining circuit. The first digital-to-analog converter is arranged to receive a first sampling clock and a digital input, and convert the digital input into a first analog output according to the first sampling clock. The at least one second digital-to-analog converter is arranged to receive the digital input and at least one second sampling clock different from the first sampling clock, and convert the digital input into at least one second analog output according to the at least one second sampling clock. The combining circuit is arranged to combine the first analog output and the at least one second analog output into a combined analog output of the digital input.
