本論文介紹了一種用於量子位元驅動的直接數字合成器 (DDS)。 為降低硬件成本,採用流水線 CORDIC 演算法結合查找表(LUT)壓縮法,硬件成本較傳統 DDS 降低 45%,並且達到 SFDR > 58 dB。此設計是一數位集成架構,所提出的高斯脈波調變器可提供輸出微波脈衝的相位、振幅和頻率的完全可編程性。此設計採用台積電 90 奈米CMOS技術實現,其中NCO的最高工作頻率為 500 MHz,功率消耗為 21.75 mW,有效面積為 0.023 mm2。為了達到 1 GHz 的數據帶寬,使用了時間交織的技術,最終,在 1 GHz 數據帶寬內實現了 58 dB 的 SFDR,可實現高保真度的量子位元控制。
This paper presents a direct digital synthesizer (DDS) for qubit drives. In order to reduce the hardware cost, the pipeline CORDIC algorithm combined with the look-up table (LUT) compression method is adopted, the hardware cost is reduced by 45% compared with the traditional DDS, and the SFDR > 58 dB is achieved. The design is a digitally integrated architecture, and the proposed Gaussian pulse modulator provides full programmability of the phase, amplitude, and frequency of the output microwave pulse. This design is implemented using TSMC 90-nm CMOS technology. The max operating frequency of the NCO is 500 MHz, the power consumption is 21.75 mW, and the effective area is 0.023 mm2. In order to achieve a data bandwidth of 1 GHz, time-interleaving technology is used. Finally, A 58 dB SFDR is achieved within a 1 GHz data bandwidth, enabling high-fidelity qubit control.
