As shown in figure: A1 forms Voltage controlled current source, A2is thevoltage comparator, A3 is the active low-pass filter. When time constant R1C1 equals to clock pulse cycle T, the relationship between input and output of circuit is: Vo=-V2E/V1. If make E = 1V, there were Vo=-V2/V1. V1 and V2 are required to bepositive, limited in 10V, the V2 is slightly below V1. Resistance R1, R2 and capacitance C1 required tousethe components with goodtemperature stability. A1 is HA2-2520,A2, A3 are LM101A.
