BJT AMPLIFIERS Sample Problems - Dr. Aydın ˙ I. Kar¸ sılayan For each circuit below, ﬁnd the small-signal transfer function v o ( s ) /v i ( s ) and sketch its magnitude bode plot. Assume β = 100 and V T = 25 mV. Also ﬁnd V o ( t ) for v i ( t ) = 10 - 3 sin(2 π 1000 t ). Simulate the circuits using PSPICE to verify your results. Provide circuit schematics and all necessary plots with measurements. Use Q2N3904 and Q2N3906 transistors for simulation.
