Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a simple BJT current mirror circuit with targeted IREF of 2 mA using a measured VBE value of 0.7 V. Specify component values for RREF and calculate the expected IOUT.

💡 Hint: Remember the relationships between the components and the VBE value.

Challenge 2 Hard

Given that the output resistance Rout typically reduces as variations in collector-emitter voltage occur, calculate the expected change in IOUT due to a change in VCE observed during testing.

💡 Hint: Reflect on the observed V-I characteristic graph shapes.
