Does 1:1 create an advantage or disadvantage? If R1 is chosen close to zero, the voltage drops too much and the error rate increases, if it rises, there will be other problems. Is there a formula for this, a mathematical datasheet data? | |

It is not clear in my mind about the others. For example, how will C2 and C5 stabilize the situation? How will it accelerate? Why is one leg of R1 connected between R2 and R3? | |
