一种采用精确前馈路径电流传感器的15–25 MHz、1 μs/0.4 A负载响应AOT升压转换器

This letter presents a high-frequency boost converter using an accurate feedforward-path current sensor for the fast-load transient response. To operate with the switching frequency of up to 25 MHz, the proposed current sensor senses the inductor current with a fast-sensing response time of about 4.5 ns. It also provides more accurate sensing gain than previous current sensors. In addition, the ad...
