Thus the output voltage v, can be set to zero even when v has a nonzero de component, (b) The three waveforms show v, the input voltage; (v + v/2), the balanced-out voltage; and vo, the amplified output voltage. If vy were directly amplified, the op amp would saturate. 3.3 Use the circuit shown in Figure E3.1 to design a de-coupled one-op-amp circuit that will amplify the +100 uV EOG to have the maximal gain possible without exceeding the typical guaranteed linear output range.
