Challenge Problems
Push your limits with challenges.
Question 1
Design a current mirror circuit ensuring a V_ON of at least 1V while maintaining an output current of 10mA. What would be the minimum supply voltage required?
💡 Hint: Consider the operation of the current mirror and its output characteristics.
Question 2
A BJT current mirror shows an output current of 5mA when the output voltage is 0.5V. If the output resistance is found to be 1k Ohm, what will be the output current at 1V?
💡 Hint: Apply the knowledge of how output current varies with voltage in BJTs.
