2 cards from this section. Quick, good the night before a test.
What type of biasing is required for the base-emitter junction of an n-p-n transistor?
Think about the voltage connection between the base and emitter.
In a p-n-p transistor, which junction must be reversed biased?
Consider the voltage polarity for p-n-p operation.
What is the required biasing for the base-emitter junction of an n-p-n transistor?
Remember the direction of current flow in n-p-n transistors.
True or False: The base-collector junction of a p-n-p transistor should be forward-biased.
Think about the polarity of voltages in p-n-p operation.
Design a circuit using an n-p-n transistor to amplify a signal from 1V to 5V. Describe the required biasing conditions and resistor values.
Consider using feedback to stabilize the gain and maintain active operation.
If a p-n-p transistor has a beta of 150 and the base current is 0.5 mA, calculate the collector current and assess if the transistor is in the active region assuming the collector voltage is 6V and emitter voltage of 8V.
Check the biasing conditions before concluding the operational state.
