Vin VA R R2 R3 С R4 VB B (a) (2 marks) Name the upper and lower op-amp circuits. (b) (3 marks) Derive the output for both the circuit. For the upper circuit, express the output VA in term of Vin. For the lower circuit, express the output VB in term of VA (c) (2 marks) Fine VAB, the potential difference between A and B, in term of Vin, and hence find the gain of the whole circuit if R1 = 10 kN and R2 = R3 = = 100 k12. = RA
