Abstract

PURPOSE:To ensure the even accuracy regardless of the level of a input voltage, by providing a digital integrating function by an up-down counter and applying negative feedback to an operational amplifying circuit. CONSTITUTION:Receiving a voltage input signal Vi, an operational amplifying circuit part 2 delivers a voltage output signal Vo'. This voltage Vo' is applied to an absolute value amplifier 3a and a voltage comparator 3d of an integral arithmetic circuit part 3. Thus an output ¦Vo'¦ is obtained from the amplifier 3a and then applied to a voltage frequency converter 3b to obtain an output SF having a pulse frequency proportional to the voltage ¦Vo'¦ through the comparator 3b. On the other hand, the comparator 3d discriminates the plus or minus of the voltage Vo' and applies a control input signal to a counter 3c. The counter 3c performs the up-counting and down-counting for the output SF when the voltage Vo' is plus and minus respectively. The output of the counter 3c is fed back to the circuit part 2 via a D/A converter 3f. As a result, no error is produced although the input voltage is particularly high.
