In practical difference amplifiers, unlike ideal difference amplifiers, when the input voltages are zero, the output voltage is not zero, which is................ called voltage.What should come in the blank? Please choose one: a. input imbalance b. output balance c. Output imbalance d. Fark e Login balance

Figure 4 shows a differential amplifier where the input voltage is Vin = Vil the output voltage is Vout - Vi2 and %3D Vo- (a) What kind of amplifier is it? Draw the small equivalent circuit and calculate the differential voltage gain G, in the case of balanced input and unbalanced output. For the calculation, consider the output resistances roi of the two transistors as open circuits (negligible current flowing in them). Show the detail of the calculation and state any assumption. (b) (c) What is Gv if you include the output resistances roi in the analysis? For the balanced input and identical transistors, the current variation in M1 and M2 are equal and opposite: i1 = -i2 (the current flowing in Rs is i- 0).
