1.1.1 Key Insight

Equation 1-5 shows that the ACOT loop gain is directly influenced by the ratio ZB/ZF, which is determined by the ripple injection and feed-forward components. Therefore, R_INJ, C_INJ and C_FF are not only used to generate the required feedback ripple, but also play an important role in shaping the control loop response, including bandwidth, stability, and transient behavior.
