    • A limiter circuit in a voltage controlled oscillator (VCO) includes a first control circuit, a second control circuit and a driving circuit having a pull-up transistor and a pull-down transistor. The first control circuit generates a first driving control signal for controlling the pull-up transistor based on an AC input signal and a first DC bias voltage. The second control circuit generates a second driving control signal for controlling the pull-down transistor based on the AC input signal and a second DC bias voltage. The driving circuit generates an output signal based on the first driving control signal and the second driving control signal. The output signal swings between a first voltage at the pull-up transistor and a second voltage at the pull-down transistor.
    • 压控振荡器(VCO)中的限幅电路包括第一控制电路,第二控制电路和具有上拉晶体管和下拉晶体管的驱动电路。 第一控制电路基于AC输入信号和第一DC偏置电压产生用于控制上拉晶体管的第一驱动控制信号。 第二控制电路产生用于基于AC输入信号和第二DC偏置电压来控制下拉晶体管的第二驱动控制信号。 驱动电路基于第一驱动控制信号和第二驱动控制信号生成输出信号。 输出信号在上拉晶体管的第一电压和下拉晶体管的第二电压之间摆动。

    • Disclosed is a method and apparatus for controlling an image forming apparatus which allows the print setting to be changed. The method for controlling the print driving of an image forming apparatus comprises the steps of monitoring whether a stop signal is input while printing one or more images corresponding to input print data; stopping print driving of the image forming apparatus when the stop signal is detected; changing print setting of the image forming apparatus as demanded by a user; and printing one or more images, which correspond to the remaining print data unprinted due to the stoppage of the print driving, by applying the print setting changed. It is possible to change the print setting of the image forming apparatus desired by a user regardless of the print driving operation of the image forming apparatus and to reflect the changed print setting to the print driving.
    • 公开了一种用于控制允许改变打印设置的图像形成装置的方法和装置。 用于控制图像形成装置的打印驱动的方法包括以下步骤:在打印与输入打印数据相对应的一个或多个图像的同时监视是否输入停止信号; 当检测到停止信号时停止图像形成装置的打印驱动; 根据用户要求改变图像形成装置的打印设置; 并且通过应用改变的打印设置来打印与由于打印驱动停止而未打印的剩余打印数据相对应的一个或多个图像。 无论图像形成装置的打印驱动操作如何,都可以改变用户期望的图像形成装置的打印设置,并且将改变的打印设置反映到打印驱动。
