Question

 Use PSpice to model the differential amplifier circuit shown in Fig. 4 in DIBO mode (double input balanced output). 
Use 2N3904 BJTs and use appropriate values for resistors (you can choose the 
values that will not lead to excessive gain and saturation) to demonstrate that the 
circuit provides differential amplification. Use Vcc = 5 and Vee = 5. Use a pair of 
sinusoids with opposing polarity (180 degree phase shift) as the inputs to the 
differential amplifier. Recall from the theory ic is needed to compute re.  Make 
sure that the conditions set in the analysis of DIBO circuit are satisfied. Assume 
 Rs1 = Rs2 50 Ω. Does your simulation match the theoretical gain? Explain any 
differences.
