(a) Assuming Isn mismatches of 64% and Isp mismatches of 65%, along with 0p 5 50, fi nd the worst-case input offset voltage for the circuit. Which is the major contribution to VOS? Hint: not all transistors intervene in the offset error. Which ones do and which ones don’t? (b) Repeat, but for the circuit.
