Challenge Problems
Push your limits with challenges.
Question 1
A transconductance amplifier is used in an application requiring a Gm of 15 mS and drives a load of 10 kΩ. If the input voltage is 40 mV, calculate both the output current and output voltage.
💡 Hint: Follow through the series of calculations step by step.
Question 2
Discuss potential circuit stability issues if a transconductance amplifier is utilized without considering its output impedance correctly.
💡 Hint: Think like an engineer: how does impedance affect circuit dynamics?
