c3) An operational amplifier structure is given according to the circuit diagram below. (55) a) Please, write the basic equations for the input parameter of an IDEAL operational amplifier. I-Consider the open switch position and: b) $$V_1$$ is set to $$0,75\mathrm{V}$$ and $$V_2$$ is set to $$1,75\mathrm{V}$$. Please, find out whether the amplifier is in its linear range in this point of operation. c) Which value of $$V_1$$ should be set in order to reach the positive saturation edge if we apply $$V_2$$ as $$2\mathrm{V}$$. II - Consider now the closed switch position and: d) Please, calculate the amplification ratio only for the inverting amplifier structure if the switch short circuits the $$70\mathrm{k}?$$ resistance and assuming $$V_2$$ is set to 0 (zero). e) Please, give the output voltage $$\left(V_0\right)$$ for the conditions described above, under point d) and with $${\mathrm{V}}_1=1,0\mathrm{V}$$
