Challenge Problems
Push your limits with challenges.
Question 1
You have a transistor with a transconductance of 15 mA/V, collector resistance of 1 kΞ©, and you want to keep the emitter resistor as high as possible while maintaining a gain of -10. What is the maximum allowed value of R_E?
π‘ Hint: Focus on rearranging the gain equation to isolate R_E.
Question 2
For the circuit with Ξ² = 200 and an input resistance of 2 kΞ©, find R_E if r_pi = 100Ξ©. What implications does this have for overall circuit stability?
π‘ Hint: Calculate R_E's impact on stability.
