Highly stable circuit uses Valvo CSA70 chopper-stabilized opamp. Required high feedback resistance is provided by R1-R2 in feedback loop. Article gives design equations.Rr' andR2 are 1 megohm, R1 is 10 ohms, and all capacitors are 0.1 μF.-K. Kraus, High-Speed Picoammeter, Wireless World, May 1976,p 78.
