Q4.1:  Referring to the Difference amplifier circuit in Figure 4.1, consider the special case where all  four resistors are equal i.e. R1 = R3 = R2 = R4. In such a scenario what is the differential mode gain    (A_{d})   transfer function of the circuit? Choose from one of the following:

Accepted Answer

A_d =\dfrac{V_o}{V_{in2}-V_{in1}}

Answer

A_d =\dfrac {V_o}{V_{in1}+V_{in2}}

Answer

A_d = \dfrac {V_o 	imes V_{in1}}{V_{in2}}

Answer

A_d = \dfrac{V_o}{V_{in1} 	imes V_{in2}}
