(a) Assuming F16 5 200, verify that IB16 in the 741 circuit of is negligibly small compared to IC4 and IC6. This allows us to defi ne the fi rst-stage input offset voltage VOS1 as the voltage difference VP 2 VN needed to make IC4 5 IC6 (not necessarily 5 9.5 A) at VC4 5 VC6 5 VBE16 1 VBE17 1 VEE. (b) Based on the above defi nition, investigate the effect of a 10% mismatch between Is1 and Is2, assuming no other mismatches in the circuit. (c) Repeat, but for a 10% mismatch between Is3 and Is4. (d) Repeat, but for a 10% mismatch between Is5 and Is6. (e) Repeat, but for a 10% mismatch between R1 and R2.
