In the given common-base amplifier circuit below, the voltage source VB is a constant voltage source that, along with the DC component of the input voltage, sets the quiescent collector current of the PNP transistor at 1 mA. The transistor has B 150, ro → ∞0, C₁ 10pF, and C₁ = 2pF. The amplifier is fed with an input source having Rin = 5k and has a 20k. Ignore the capacitance C₁ and use VT = 25mV. Derive the transfer function and answer the load resistance RL questions below. VIN = = Rin m What is the DC gain? +1 VB dB What is the frequency of the dominant pole? RL -OVOUT CL
