EXAM 2 ECE 331 QUESTIONS ANSWERED CORRECTLY LATEST UPDATE 2026 BJT transconductance $g_m$ - Answers $g_m = I_C / V_{th}$ where $V_{th} approx 25$ mV at room temperature. Higher $I_C$ means higher $g_m$. BJT small-signal base resistance $r_pi$ - Answers $r_pi = beta / g_m = beta V_{th} / I_C$. Large when $I_C$ is small, small when $I_C$ is large. BJT output resistance $r_o$ - Answers $r_o = V_A / I_C$ where $V_A$ is the Early voltage. Larger $r_o$ at lower bias current...
