Challenge Problems
Push your limits with challenges.
Question 1
Design a circuit using a BJT to amplify a weak input signal of 0.1V to an output of 2V. What values would you choose for R_C and Ξ²?
π‘ Hint: Use V = I * R for your calculations.
Question 2
If the input signal at the base oscillates between 0.3V and 0.7V, how will this affect the output voltage, assuming the transistor remains within its active region?
π‘ Hint: Use concepts from small-signal analysis to illustrate the variation.
