OPTICALLY CLOCKED DIGITAL-TO-ANALOG CONVERTER AND DDS UNIT HAVING SUCH A CONVERTER

摘要

The invention relates to a digital-to-analog converter (30), comprising a first return-to-zero stage (31₁), which is connected to a first bus bar (32₁), wherein the first bus bar (32₁) is connected to one first output each of several difference stages (35₁, 35₂, 35_n). The first return-to-zero stage (31₁) has at least one clock input, which is connected directly or indirectly to a first photodiode, wherein the first photodiode is fed by a pulsed light source (5).
