Circuit for small current and voltage conversion

Probe current voltage pin 420*4450 head diameter 5.0 over current current and voltage pin

The figure shows that the circuit output amplifier used for small current and voltage conversion is often used as a buffer to amplify the voltage by a factor of 10, but try to make the amplification factor 1 as much as possible.
Limit the parallel capacitor C on R1~R4 and find the capacitance value according to the formula.
