Question 1
Calculate the transconductance of a BJT if the collector current increases from 1mA to 1.5mA with an input voltage change of 0.1V.
💡 Hint: Use the formula gm = ΔIc / ΔVin.
Question 2
If a BJT changes from active to saturation when the input increases past a certain level, how might this affect circuit behavior?
💡 Hint: Think about what saturation means for an amplifier's performance.
