Challenge Problems
Push your limits with challenges.
Question 1
Design a Wien Bridge oscillator for a target frequency of 10 kHz, selecting suitable resistor and capacitor values.
💡 Hint: Use the formula f0 = 1/(2πRC) to relate frequency with R and C values.
Question 2
Calculate the output resistance Rout for a simple current mirror currently set to output 1.5 mA with variation from the load affecting VCE.
💡 Hint: The flatter the line, the less the current changes with voltage—this influences output resistance.
