please answer all questions. much thanks
Question 4 The difference amplifier in Figure 5 has parameters Ri = Rs = 10kg and Ri 21kN . R = 20522 21 R R V2 R R Figure 5 Determine V, when:- Vn=1V, V12 =-1V (7 marks) (u) Vn= V2 = IV (s marks) (b) Determine the common-mode gain. (4 marks) Hint: V_=V = V12, common-mode gain = V. IV.) (c) Show mathematically that the design of circuit in Figure Sousing resistor ratio in the circuit, can turn the Op. amp circuit to a difference amplifier with equation of V.=(R, R)(V12-V11). (9 marks)
