专利汇可以提供Operation unit专利检索,专利查询,专利分析的服务。并且PURPOSE:To enable to perform A/D conversion of high sensitivity at all times independently of the smplitude of the set value for the operation constant signal and accordingly, the operation of high precision, by constituting that the signal dividing the output of the D/A converter is fed to the other input terminal of the comparator. CONSTITUTION:The operation constant Kp is set by giving the output eo of the D/A converter 4 to the resistance dividing voltage means 5 and feeding the voltage dividing signal eo/Ko to other input terminal of the comparator 20. Accordingly, in performng A/D conversion for the operated signal e1, the A/D conversion loop constituted with the comparator 20, processor 3, converter 4 and means 5 performs the A/D conversion so that eo=Ei Kp can be obtained finally. The characteristic curve representing the relation between ei and eo moves as the arrow a when the set value of Kp is increased, and this is similar to the input and output performance when the feedback rate is changed in a feedback amplifier. For example, taking the resolution of A/D conversion as 10-bit, the A/D conversion of high resolution such as 0.1% can be realized independencly of the set value of Kp.,下面是Operation unit专利的具体信息内容。
