Suppose, to reduce power, the lengths of the current sources used in the amplifiers seen in Fig. 24.50 are increased from 2 to 10. Will the AC performance of the op-amp used to generate Fig. 24.53 change with this modification? Why or why not? Verify your answer using a SPICE simulation. Compare the currents used in the modified op-amp (with the lower power GE diff-amps) to the current seen in Fig. 24.53.
