A current mirror circuit consists of two BJTs. The reference current is set to 3mA, but due to current losses, the output is observed to be only 2.5mA. If a Beta-helper transistor is added, how will it likely affect the output current?
💡 Hint: Consider how the Beta-helper circuit addresses current losses.
You are tasked with designing a current mirror that requires an output current of 5mA and a minimum combined voltage of 2.5V from three different voltage sources. What factors will you consider when selecting transistors for this design?
💡 Hint: Think about saturation voltages and their impact on circuit function.
