Consider the amplifier of Fig. 9.40, whose parameters are specified in Example 9.6. If a manufacturing error results in the W/L ratio of Q7:
being 48/0.8, find the current that Q7: will now conduct. Thus find the systematic offset voltage that will appear at the output. (Use the results of Example 9.6.) Assuming that the open-loop gain will remain approximately unchanged from the value found in Example 9.6, find the corresponding value of input offset voltage, VOS.
