For the circuit in picture (a), it uses double power supply, in-phase input, its amplification factor is:V=+Ua/Ue=(R1+R2)/R2, 1MΩ>R3>10kΩ, R2>1kΩ, V<200.For the circuit in picture (b), it uses double power supply, out-phase input, so:V=Ua/Ue=R1/R2, 1MΩ>R3>10kΩ, R2>1kΩ, V>200.For the circuit in picture (c), it uses single power supply, in-phase input, so:V=+Ua/Ue=(R1+R2)/R2, 1MΩ>R3 and R3>10kΩ, R2>1kΩ, V<200, 1/wC1<0.5R2.For the circuit in picture (d), it uses single power supply, out-phase input, so:V=-Ua/Ue=R1/R2, 1MΩ>R3 and R3>10kΩ, R2>1kΩ, V<200, 1/wC1<0.5R2.
