    • A CMOS-ECL converter contains a drive stage modified from the prior art and a connected output transistor. The driver stage comprises a resistor element and an n-channel field effect transistor. The resistor element can preferably be constructed with the assistance of a p-channel field effect transistor and is connected in series with the n-channel field effect transistor. The advantage of such an arrangement is that the capacitive load at the input of the CMOS-ECL converter is low because the resistor element or, respectively, the p-channel field effect transistor, offers no contribution to such an input load. The channel width of the p-channel field effect transistor can be set such that an adequately-high base current for the bipolar output transistor can be supplied.
    • CMOS-ECL转换器包含从现有技术修改的驱动级和连接的输出晶体管。 驱动器级包括电阻元件和n沟道场效应晶体管。 电阻元件优选地可以在p沟道场效应晶体管的辅助下构成,并与n沟道场效应晶体管串联连接。 这种布置的优点在于,CMOS-ECL转换器的输入处的电容性负载较低,因为电阻元件或分别为p沟道场效应晶体管对这种输入负载没有贡献。 可以设置p沟道场效应晶体管的沟道宽度,使得可以提供用于双极性输出晶体管的足够高的基极电流。

    • A first comparator compares a voltage of a pair of primary terminals of a pulse transformer with a first reference voltage, to apply an output voltage corresponding to the voltage difference therebetween to a gate of an N channel MOSFET. The N channel MOSFET is responsive to the output voltage for controlling current flowing through a primary side of a pulse transformer. Consequently, even if the impedance of a load connector to a pair of secondary terminals of the pulse transformer is fluctuated, a voltage between the pair of secondary terminals is kept constant. A second comparator compares the output voltage of the first comparator with a second reference voltage, to apply an output voltage corresponding to the voltage difference therebetween to a gate of a P channel MOSFET. When the load impedance becomes low, the P channel MOSFET performs control such that the output voltage of the second comparator does not exceed a predetermined value. Consequently, current flowing through the primary side of the pulse transformer is limited not to exceed a constant value. Thus, a voltage between output terminals does not exceed a constant value.
    • 第一比较器将脉冲变压器的一对初级端子的电压与第一参考电压进行比较,以将对应于其电压差的输出电压施加到N沟道MOSFET的栅极。 N沟道MOSFET响应于输出电压来控制流过脉冲变压器初级侧的电流。 因此,即使负载连接器对脉冲变压器的一对二次端子的阻抗波动,一对次端子之间的电压保持恒定。 第二比较器将第一比较器的输出电压与第二参考电压进行比较,以将对应于其电压差的输出电压施加到P沟道MOSFET的栅极。 当负载阻抗变低时,P沟道MOSFET进行控制使得第二比较器的输出电压不超过预定值。 因此,流过脉冲变压器的初级侧的电流被限制为不超过常数值。 因此,输出端子之间的电压不超过常数值。

    • An input translating circuit for a CMOS device is disclosed which can be operated without being influenced by a level of the supply voltage. This is made possible by providing a supply voltage level discriminating means consisting of a voltage dividing network for dividing the supply voltage into predetermined voltages and a level comparing means for comparing the divided voltage with the reference voltage level, and further by providing a constant voltage supply means, so that a trip voltage, used in the operation of the circuit, can be maintained at a constant level regardless of the variations of the supply voltage. Further, the circuit according to the present invention eliminates corresponding mask work requirements for the option of the power voltage in the manufacturing process, thereby lowering production complexity costs.
