Micro-power-consumption current reference starting circuit

A micro-power-consumption current reference starting circuit comprises a reference circuit and a starting circuit, and the reference circuit comprises a conduction unit, a clamping unit, an operational amplifier unit and a current output tube; and the starting circuit is used for providing a starting current for the reference circuit based on a pre-starting current in a micro-power consumption state so as to start the reference circuit, and disconnecting the starting current after identifying that the circuit is started. According to the current reference starting circuit, good and stable starting current can be provided for the reference current source in a micro-power-consumption environment, and therefore normal starting of the reference current source is guaranteed. 一种微功耗的电流基准启动电路，包括基准电路和启动电路，所述基准电路，包括导通单元、钳位单元、运放单元和电流输出管；所述启动电路，用于在微功耗状态下基于预启动电流为所述基准电路提供启动电流以启动基准电路，并在识别到电路启动后断开所述启动电流。本发明中电流基准启动电路，能够在微功耗环境下为基准电流源提供良好且稳定的启动电流，从而保证基准电流源的正常启动。
