The simulation results are shown in Fig. 30.72. The ratio of $C_I$ to $C_F$ is one and so, ideally, the output is just twice as large as the input. The output should swing from 1 V down to -1 V. However, because of the 50 mV offset, which is also multiplied by a factor of 2, the output is shifted downwards so that it swings from 0.9 V to -1.1 V.
