Question

Problem 14.2 - A CE amplifier utilizes a BJT with \( \beta=100 \) and \( V_{A}=100 \mathrm{~V} \), is biased at Ic \( =1 \mathrm{~mA} \) and has a collector resistance \( \mathrm{Rc}=5 \mathrm{k} \) and is fed with a signal source having a resistance of \( \mathrm{Rsig}=5 \mathrm{k} \). 1) What value of \( \operatorname{Re} \) is required to rise Rin to a value 4 times that of Rsig? 2) Find Ro and Avo. 3) If the amplifier is connected to a load \( \mathrm{R}_{\mathrm{L}}=5 \mathrm{k} \). Find the resulting \( A v \) and Gv. 4) If \( v_{i} \) is limited to \( 40 \mathrm{mV} \) what is the corresponding \( v_{s i g} \) and \( v_{o} \) when the load is connected.
