2、位设计的要求本论文在逐次逼近算法上对传统的,二进制搜索算法进行优化并且证明在芯片面积大大减小的条件下优化后,的算法能实现完全相同的功能考虑到寄生电容的影响和工艺偏差论文中还提,,出了祸合电容误差校准算法并引入权电容失配校准算法用以提高的精度。在高精度,的设计中算法与实际电路的紧密结合也是整个设计中的。,重要环节在总体电路设计的基础上论文在传统的电荷重分布式逐次逼近的基础上加入误差校准电路以及相应的误差存储和误差积累电路,用以实现权电容失配校准算法祸合电容误差校准算法主要是针对中三个关键节点存在的寄生电容,所以在寄生参数提取后对核心电容进行版图优化时,。根据计算值对两个重要的
3、藕合电容值进行优化实现了祸合电容误差校准算法,这些算法对电路性能的提高在位电荷再分配逐次逼近型的设计中通,过环境下的仿真工具进行后仿真得到了验证并且在电路设计上确保位精度的实现。,,最后芯片在工艺上流片成功并在搭建的测试平。,台上对芯片进行了测试在功能测试上芯片的模数转换功能得以实现,,,在参数测试上虽然受测试条件和测试系统噪声限制个别参数无法精确测出。,但测试数据显示芯片的许多静态和动态参数较好芯片最后通过调试成功应四川大学硕士学位论文用于一个高精度的实时信号采集系统中。、、、关键词算法逐次逼近电荷再分布高精度四川大学硕士学位论文,,,加,,,知,哪,,娜拼加少四川大学硕
