摘要： The present method reduces variations in noise and temperature in a mixed-signal circuit including memory. Memory electrically proximate an analog circuit is provided and a digital data word received at the memory. When the data word is not a desired data word, a dummy write to the memory is performed. When the data word is a desired data word, the data word is written to the memory. The mixed-signal circuit includes an analog circuit, memory electrically proximate to the analog circuit and connected to receive digital data words, and a memory controller connected to the memory. The memory controller is operable to cause the memory to write to the memory each of the data words that is a desired data word and additionally to perform a dummy write to memory for each of the data words that is not a desired data word.
摘要翻译：本方法减少包括存储器在内的混合信号电路中的噪声和温度变化。提供电接近模拟电路的存储器和在存储器处接收的数字数据字。当数据字不是期望的数据字时，执行对存储器的虚拟写入。当数据字是期望的数据字时，数据字被写入存储器。混合信号电路包括模拟电路，电气地靠近模拟电路并被连接以接收数字数据字的存储器以及连接到存储器的存储器控制器。存储器控制器可操作以使存储器向存储器写入作为期望数据字的每个数据字，并且另外对于不是期望数据字的每个数据字执行对存储器的虚拟写入。
