1. How might the input offset current of Figure 2.5.1 be reduced?
2. What are some causes of output offset voltage in the circuit of Figure 2.5.1?
3. What are the effects if the two collector resistors not identical in value?
4. What is the significance of a high CMRR?
5. How significant is the change in CMRR when using the improved current source? Based on the improvement, estimate the internal impedance of the current source.
