Challenge Problems
Push your limits with advanced challenges
Design a circuit using the Common Gate amplifier configuration that achieves an input impedance of 500Ω and requires output swing of ±8V from a 15V supply. Calculate necessary resistor values and explain your reasoning.
💡 Hint: Use Ohm's Law and the input-output impedance relationships.
If the Common Base amplifier needs to maintain at least 90% efficiency with an output swing of ±6V, calculate the minimum DC supply voltage required for the given circuit constraints.
💡 Hint: Think about how supply voltages directly affect output capabilities.
