    • A DA converter for converting an inputted digital signal to an analog signal includes an integrator which outputs the value of integral of the digital signal every fixed cycle, a level comparison part which judges whether the value of integral outputted by the integrator has come into the state of exceeding a predetermined reference value, a feedback part which subtracts a predetermined value from the value of integral according to the compared result obtained by the level comparison part, a timing information generation part which generates timing information on a variation point of transition from the value of integral of each cycle outputted by the integrator and the value of integral in a cycle just before each cycle into the state of exceeding by time resolution smaller than the predetermined cycle, a timing generation part which generates a timing signal by the time resolution smaller than the predetermined cycle according to the timing information, and a signal processing part which generates the analog signal according to the timing signal.
    • 用于将输入的数字信号转换为模拟信号的DA转换器包括:每个固定周期输出数字信号的积分值的积分器;判定积分器输出的积分值是否已经达到状态的电平比较部分 超过预定参考值的反馈部分,根据由电平比较部分获得的比较结果从积分值中减去预定值的反馈部分;定时信息生成部分,生成关于从值的变化点的定时信息 积分器输出的每个周期的积分和在每个周期之前的循环中的积分值进入超过比预定周期小的时间分辨率的状态;定时产生部,其通过时间分辨率小于 根据定时信息的预定周期,以及信号处理部分w 根据定时信号产生模拟信号。
