When using a transistor as a linear amplifier, it is important to avoid driving the transistor into either cutoff or saturation. Since most signals that are amplified are time varying, the maximum excursions of the time-varying signal should be known. In this problem, the time-varying signal is a 3-V sinusoid, v_S = 3 cos ωt V.

To avoid driving the transistor into cutoff, a dc bias voltage vBias is added in series with the sinusoid. Your task is to select appropriate values for vBias and R_B.

Your choices should be the smallest bias voltage necessary to prevent cutoff and a sufficient base resistor to avoid saturation. The parameters of the transistor in Figure P4-24 are β = 90 and V_γ = 0:7 V.

After selecting appropriate values for vBias and R_B, find the maximum and minimum values of v_O for v_S = 3 cos ωt V.
