    • Disclosed is a hybrid integrated circuit device provided with an active filter. The active filter is constructed mainly from a rectifier circuit, a reactor with one terminal connected with an output terminal of the rectifier, a switching element connected with one terminal of the reactor and a smoothing condenser connected with the other terminal of the reactor. The active filter is mounted on an insulating metal substrate and has, other than the above feature, a specific circuit structure wherein the substrate is divided by a ground pattern or power supply pattern into two blocks. One block is for a large current circuit such as the rectifier circuit, the switching element, and a diode and another block for a small signal circuit such as a control circuit. The hybrid integrated circuit device is of remarkably compact size. Also, it is greatly superior in a noise performance because switching noise does not flow into the chassis of electronic equipment from the metal substrate and the control circuit is shielded from the noise produced by the large current circuit, and also because the noise caused by wiring inductance can be limited.
    • 公开了一种具有有源滤波器的混合集成电路装置。 有源滤波器主要由整流电路,一端与整流器的输出端连接的电抗器,与电抗器的一端连接的开关元件和与电抗器的另一端连接的平滑电容器构成。 有源滤波器安装在绝缘金属基板上,并且除了上述特征之外,具有特定的电路结构,其中基板被接地图案或电源图案划分成两个块。 一个块用于诸如整流器电路,开关元件和二极管之类的大电流电路,以及用于诸如控制电路的小信号电路的另一块。 混合集成电路器件尺寸非常紧凑。 此外,由于开关噪声不从金属基板流入电子设备的底盘,并且控制电路被大电流电路产生的噪声屏蔽,并且还因为布线引起的噪声,噪声性能非常优越 电感可以受到限制。
