The picture shows division circuit. A1 composes voltage-controlled current source. A2 composes voltage comparator. A3 composes active low pass filter. When the time constant R1C1 is equal to clock pulse period T, the relation of the output and input is: Vo=-V2E/V1. If E is made to be 1V, then Vo=-V2/V1. V1 and V2 are both required to be positive and are restricted within 10V. V2 is a little lower than V1. The resistor R1,R2 and capacitor C1 is required to use components with good temperature stability. A1 is HA2-2520. A2,A3 are LM101A.
