2.103 Using offset-nulling facilities provided for the op amp, a closed-loop amplifier with gain of+1000 is adjusted at 25°C to produce zero output with the input grounded. If the input offset-voltage drift is specified to be 20 μV/°C, what output would you expect at 0°C and at 100°C? While nothing can be said separately about the polarity of the output offset at either 0 or 75°C, what would you expect their relative polarities to be?
