2 cards from this section. Quick, good the night before a test.
Define voltage gain in the context of a common emitter amplifier.
Think about how output voltage is determined based on input voltage.
What does transconductance (g_m) measure?
It relates to the operation of the transistor's collector current.
What is the formula used to calculate voltage gain in a common emitter amplifier?
Consider the key parameters that dictate how voltage gain is achieved.
Is it true that increasing I_C increases the voltage gain?
Focus on the relationship between current and gain metrics.
Design a common emitter amplifier that meets the following specifications: A voltage gain of 50, supply voltage of 15 V, and a minimum output swing of ± 5 V. Calculate necessary component values.
Analyze the required gain and set up your equations accordingly.
Calculate the maximum power dissipation in a CE amplifier with a maximum I_C of 2 mA and a supply voltage of 12V, and discuss potential design implications if power dissipation exceeds recommended levels.
Consider checking the thermal characteristics of your devices.
