Power Supply Considerations

A capacitor CG is added in the gain network to ensure a unity gain in low frequency to keep the right DC

component at the ouput. CG contirbutes to a high pass filter with Rfb//RG and its value is calculated with a

consideration of the cut off frequency of this low pass filter.
