4 cards from this section. Quick, good the night before a test.
Define transconductance and explain its significance.
Think about the relationship between input voltage and output current.
What is the output conductance in terms of collector current and collector-emitter voltage?
Recall the ratio definition.
What does output conductance measure?
Think about what current behavior you want to study.
True or False: Transconductance is defined as the slope of the I_C vs. V_BE curve.
Recall the definition discussed in class.
A BJT has a collector current of 1mA at a particular Q-point. If the V_BE varies by 0.1V, calculate the transconductance assuming the collector current varies to 1.2mA.
Use the formula ΔI_C / ΔV_BE.
Given a BJT with early voltage (V_A) of 100V, and the collector current increases from 10mA to 12mA as V_CE increases from 5V to 15V, determine the output conductance.
Recall how output conductance is defined with respect to I_C and V_CE.
