Challenge Problems
Push your limits with advanced challenges
Given a common source amplifier setup with a threshold voltage of 1.5V, an aspect ratio K of 0.25, and varying input voltages of 2V, 3V, and 4V, calculate the output voltage for each input assuming a load resistor of 10 Ohms.
💡 Hint: Calculate I_DS for each input voltage first and then use Ohm's law for V_out.
Analyze a scenario where the channel length modulation effect is significant. If the drain current is observed to increase with a change in V_DS while having a fixed V_GS, what could be the implications for circuit design?
💡 Hint: Think about how you would design for predictable behavior with varying currents.
