摘要： A multislope A/D converter is presented which employs a multislope integration technique enabling the use of a single comparator to detect polarity changes in the integrator output voltage. The run-up interval of the integrating A/D converter is controlled by a four-step pattern that is repeated as many times as is required in order to keep the integrator output voltage within the confines of a preselected voltage range. During the first step of the four-step pattern, a positive reference charge is applied to the integrator. In the second step, a decision is made as to whether to either maintain the application of the positive reference charge to the integrator or to change over to the negative reference charge. The decision is determined such that the reference charge causes the integrator output voltage to move toward or through a preselected target voltage range. The third step is to either connect the negative reference charge to the integrator or to maintain the application of the negative reference charge. The fourth step is to decide whether to either leave the negative reference charge connected or to switch back to the positive reference charge. The preceding decision is decided such that the reference charge causes the integrator output voltage to move toward or through the preselected target voltage range. The time duration for each step can be equal or different depending on the requirements of the A/D converter.

摘要翻译： 提出了一种多斜率A / D转换器，采用多边积分技术，可以使用单个比较器来检测积分器输出电压的极性变化。 积分A / D转换器的启动间隔由四步模式控制，四步模式重复所需的次数，以便将积分器输出电压保持在预选电压范围的范围内。 在四步模式的第一步中，积分器应用正参考电荷。 在第二步骤中，决定是否将积极参考费用的应用维持在积分器上，或者将其转换为负参考费用。 该判定被确定为使得参考电荷导致积分器输出电压朝向或经过预选的目标电压范围移动。 第三步是将负参考电荷连接到积分器或维持负参考电荷的应用。 第四步是决定是否要连接负参考电荷或者切换回正参考电荷。 决定上述判定，使得参考电荷导致积分器输出电压朝着或经过预选的目标电压范围移动。 每个步骤的持续时间可以根据A / D转换器的要求相等或不同。
