    • A current generator (CG) is composed of a constant-current-source transistor M1, and transistors (M2, M3). On receipt of control signals (VG2, VG3) respectively from a driver circuit (not shown), the transistors (M2, M3) complementarily operate to function as current switches. Then, damping resistance (R3) is provided between the drain electrode of the transistor (M3) and an output terminal ({overscore (IT)}). The output terminal ({overscore (IT)}) is connected to a ground (GND), while an output terminal (IT) is grounded via an external terminal (R2). Such a structure allows a semiconductor integrated circuit device to reduce its output ringing and further to suppress imperfections resulting from the adoption of the structure to reduce the ringing.
    • 电流发生器(CG)由恒流源晶体管M1和晶体管(M2,M3)组成。 分别从驱动电路(未示出)接收到控制信号(VG2,VG3)时,晶体管(M2,M3)互补地工作,起到电流开关的作用。 然后,在晶体管(M3)的漏电极和输出端({overscore(IT)}之间设置阻尼电阻(R3)。 输出端子({overscore(IT)})连接到地(GND),而输出端(IT)通过外部端子(R2)接地。 这种结构允许半导体集成电路器件减少其输出振铃并且进一步抑制由采用该结构导致的减少振铃的缺陷。
