AI Technical Summary
Existing quantum computing devices have large and expensive high-stability voltage generators, which are not conducive to the integration of multi-channel systems. Furthermore, the deployment of development board-level multi-channel DAC chip systems is complex and has limited integration, making rapid deployment difficult.
Employing chip-level high-stability voltage design modules, noise control design modules, and hardware decomposition design modules, and through a three-level circuit design consisting of a reference and amplification circuit, a 4-channel integrated voltage board, and a front-end functional board, combined with miniature coaxial cables, differential lines, and grounding design, high signal integration and noise suppression are achieved. A unified interface and modular design are used to improve scalability.
It achieves highly integrated multi-channel devices, reducing the cost per channel to one-fifth of that of commercial instruments. It boasts good stability, strong scalability, and can be rapidly deployed to meet the needs of quantum computing.
