Low-delay reference output circuit and output method

The invention provides a low-delay reference output circuit and an output method. The low-delay reference output circuit comprises a reference voltage power supply circuit, a delay circuit, a trigger and a filter circuit, the trigger outputs different control signals to control the delay circuit to adjust the filter circuit to be in different impedance states, and the filter circuit boosts or filters reference voltage input into the filter circuit according to the impedance states. And in a low-resistance state, the reference voltage is quickly boosted after being connected to the filter circuit, so that the starting requirement of a circuit needing to be quickly started is met. 本发明提供一种低延迟基准输出电路与输出方法，包括基准电压供电电路、延迟电路、触发器和滤波电路；触发器输出不同的控制信号控制延迟电路调整滤波电路处于不同的阻抗状态，滤波电路根据所处的阻抗状态对输入至滤波电路中的基准电压进行升压或滤波。在低阻状态时，基准电压接入滤波电路后快速升压，满足需要快速启动的电路的启动需求。
