    • A circuit and a method are disclosed for a Schmitt trigger stage which converts transistor-transistor logic (TTL) into metal oxide semiconductor (MOS) logic signal levels using all MOS devices. The circuit reduces the standby current of the n-channel transistor of the input section of the Schmitt trigger stage by adding a MOS diode to the bottom the input section. When higher than normal supply voltages are used, the standby current of the p-channel transistor of the input section can be reduced by adding a MOS diode to the top of the input section. In addition, a small MOS transistor, connected across the output Schmitt trigger inverter, eliminates leakage currents in that inverter.
    • 公开了用于施密特触发级的电路和方法,其使用所有MOS器件将晶体管晶体管逻辑(TTL)转换为金属氧化物半导体(MOS)逻辑信号电平。 该电路通过向输入部分的底部添加MOS二极管来降低施密特触发级的输入部分的n沟道晶体管的待机电流。 当使用高于正常电源电压时,可以通过向输入部分的顶部添加MOS二极管来减小输入部分的p沟道晶体管的待机电流。 另外,一个连接在输出施密特触发器上的小型MOS晶体管消除了该逆变器的漏电流。
