... #### Why are transistors in differential pair are “Identical”? Explain briefly

Transistors in differential pair are identical because 1.to maximize common mode rejection ratio 2.to increase the differential input resistance 3.to ... #### The initial voltage across the capacitor is v(0) =12 V in the circuit. Find the voltage v(t) across the capacitor for t ≥0.

... #### Suppose that s(t) is modulated again, this time via multiplication with a cosine of frequency fı. What is the resulting magnitude spectrum? Hint: let γ(t) s(t) cos(2r/t), and apply (2.5) to find R(f)

... #### EECE 3211 Design Project Design a BJT amplifier. The input resistance is should be 1kΩ and the output resistance should be 2.2k. The voltage gain as described below should be -10. Submit a report describing and defending your design. It should include computer simulations of sufficient detail to support your claims of the design’s effectiveness. Av =Vo / Vi = -100
