Challenge Problems
Push your limits with advanced challenges
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 β?
💡 Hint: Use V = I * R for your calculations.
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?
💡 Hint: Use concepts from small-signal analysis to illustrate the variation.
