Challenge Problems

Push your limits with challenges.

Question 1

In a given circuit, with a supply voltage of 18V and a required output swing of 10V, calculate the necessary resistor values if the target current is 1.2 mA.

💡 Hint: Utilize Ohm's law and the principles of voltage division to approach the solution.

Question 2

If the input resistance of the amplifier is 15 kΩ, how does this value influence the choice of coupling capacitors when aiming for a lower cutoff frequency of 5Hz?

💡 Hint: The lower the frequency, the larger the capacitance required, which links R and C directly.
