$\backslash$#$3-$III. Small Signal Amplifier Analysis $($hand calculation$)$

Use the hybrid$-$pi small signal BJT model and perform the small signal circuit hand calculations. Sketch your hybrid$-$pi circuit model. Use the rules that you learned in class $($short all DC voltage sources and open all DC current sources and assume that the coupling capacitors act like a short to the small signal for the frequencies of interest$).$ From your circuit model, determine the voltage gain Vout$/$Vs and Vout$/$VBin in V$/$V and compare your results to the PSPICE simulation.
