R1C1 equal to the clock pulse period T, the relationship between the output and the input of the circuit is: Vo -V2E/V1, so that if E 1V, there Vo -V2/V1, V1, V2 are positive requirements and limited to less than 10V, V2 is slightly lower than V1. Resistors R1, R2 and capacitor C1 requires a temperature stable element. A1 is HA2-2520, A2, A3 for the LM101A.
