\u00a0 \u00a0 The scientific article is devoted to the study of one of the main functional units of the direct digital frequency synthesizer – digital-to-analogue converter (DAC). The architecture of a direct digital frequency synthesizer using a nonlinear DAC is proposed. To build a nonlinear DAC, the use of a divider attenuator is proposed, which consists in the use of coded switching of the points of intermediate connections of a line of series-connected resistors of the same denomination. The main functional unit of the DDS is the phase accumulator. The unsolved problem of the phase accumulator is the problem of the speed of propagation of the transfer signal from the discharge to the discharge of the terms. Increasing the speed of DDS is possible in the following way: increasing the speed of the phase battery and reducing its power consumption, reducing the size of the permanent storage device of the phase-amplitude converter, choosing the optimal DAC structure. Reducing energy consumption is one of the most important tasks when designing a DDS. Phase battery and DAC units have the highest power consumption in a direct digital frequency synthesizer, although the DC storage unit also has a significant power consumption. When developing high-speed DDS, two main approaches to their structure are also developed and competing – with the use of ROM and without the use of ROM. In the second case, most developments use a nonlinear DAC, which solves the problem of forming the structure of the harmonic signal and digital-to-analogue conversion.<\/em>
