Output circuit having short rise time and small consumption current
摘要：
A current mirror circuit includes p-type MOS (PMOS) transistors, whereby the current flowing when the input voltage is “H” is interrupted when an output node of the current mirror circuit goes from “L” to “H,” so that a cascode-connected PMOS transistor within the current mirror circuit is automatically turned OFF. The gates of PMOS transistors within the current mirror circuit are connected by a signal line directly to the output node. The rise time of the output voltage of the current mirror circuit and the consumption current can thus be reduced.
摘要（中）：

电流镜电路包括p型MOS（PMOS）晶体管，当电流镜电路的输出节点从“L”变为“H”时，当输入电压为“H”时流动的电流被中断，使得 电流镜电路内的共源共栅PMOS晶体管自动关断。 电流镜电路内的PMOS晶体管的栅极通过信号线直接连接到输出节点。 因此可以减小电流镜电路的输出电压的上升时间和消耗电流。
