Question 4 The difference amplifier in Figure 5 has parameters R1 = Rs = 10k12, R2 = 2012 , and R-21622 w R R w V. V12 w R R Figure 5 (a) Determine V, when:- (1) V. = 1V, V12=-1V (7 marks) (5 marks) (ii) V-V2 - IV (b) Determine the common-mode gain. (4 marks) (Hint: V.= V1 = V12, common-mode gain = V./ Vom) (e) Show mathematically that the design of circuit in Figure 5, using resistor ratio in the circuit, can turn the Op. amp circuit to a difference amplifier with equation of V.=(R/R)V12-V.).
