具有涟漪注入的底部检测控制的固定导通时间由于陶瓷电容器解决方案的实际使用和实现而变得非常有吸引力，同时保持超快的瞬态响应。本文在比较器运算中引入平均法，对传递函数进行了定量分析。结果，定量地揭示了频率响应特性。理论计算结果与实际测量结果吻合较好。
The fixed on-time with bottom detection control having ripple injection has become very attractive due to practical usage and realization of ceramic capacitor solution for output while keeping ultra fast transient response. This paper presents quantitative analysis by introducing averaging method in comparator operation for the transfer function. As a result, the frequency response characteristic was quantitatively revealed. Good agreements between theoretical results and actual measurements were obtained.
