The current dumping circuit was calculated from R8, R6, CH2 and U1B as C. It was hard to estimate the integrating level from the OP but it seems as the Current Dumping Bridge is in balance. In the tests i had R8 as a trimmer but i believe it would be better to adjust R6 if you want to check the working order. The value of R5 is determined by the size of the signal between the OP:s. I want a small signal so it is possible to see the correction signal for the OP2. The smaller the resistor the smaller signal. But the Op needs the same amount of input signal to make ± 0,6v at the output.
Nowadays i dont calculate so precise anymore. I got the hands on EWB (later developed to Multisim) in 1995 and after that the simulator does the hard work for me. So amplification for me is simplified to R2/R1+1 + the simulator for a noninverting amplifier.
