The purpose of this study is to investigate the benefits and drawbacks associated with applying CMFB in entirely differentiated three-stage OTAs using two loops. Specifically, the investigation will focus on determining which configuration, a single loop or two loops, yields the best results. The advantages of each method are dissected, and the ways in which they affect stability, linearity, noise, and CMR are taken into account. The results indicate that a multi-loop CMFB has the potential to enhance the filter 1-dB compression when compared to a single loop, which shows that this improvement is possible. In spite of the fact that the differential path was not altered in any way, this improvement was nonetheless accomplished.
