Challenge Problems
Push your limits with challenges.
Question 1
A current mirror has the following specifications: V_supply = 12V, R_bias = 19kΩ, and I_ref = 1mA. Calculate the output current if the load remains constant regardless of voltage changes.
💡 Hint: Consider resistor drop and apply Ohm's law.
Question 2
You need to design a current mirror that maintains a precise output current of 500µA. Specify the transistor types, bias voltage, resistor values, and relevant calculations to achieve this.
💡 Hint: Ensure the chosen components support operational stability.
