摘要： A pre-buffer level shifter and an I/O buffer apparatus are provided. The pre-buffer level shifter includes a switchable current source, a current mirror, a buffer unit, a first clamping circuit and a second clamping circuit. Because of a clamping circuit inside a thin oxide MOS transistor device of the pre-buffer level shifter, the present invention can control the voltage swing of the signal for driving an output buffer within a suitable voltage range. Thus, the pre-buffer level shifter can correctly drive the output buffer made of thin oxide MOS transistor devices, increase the operating speed and ensure the reliability thereof.

摘要： The high-speed, low setup time, voltage-sensing flip-flop of an embodiment of the present invention comprises a master stage and a slave stage. The master stage has a data input and a clock input. The slave stage receives two signal lines from the master stage. When the clock input is low, the two input lines to the slave stage are pulled high. This turns on two transistors and precharges the inputs to the slave stage. When the clock makes a high transition, the pullup transistors in the master stage are turned off which decouples the inputs of the slave stage from the output of the master stage. At this time, if the data input is high, the A input to the slave stage is discharged. If the data input is low, the B input to the slave stage is discharged. After the two inputs to the slave stage are decoupled from the master stage, any change in the data input signal causes the inputs to the slave stage to float low since the two lines are not pulled high or low. In this way, the inputs to the slave stage are precharged and discharged on every clock cycle. This precharging results in a nearly zero setup time.
摘要翻译：本发明实施例的高速，低建立时间，电压感测触发器包括主级和从级。主级具有数据输入和时钟输入。从站从主站接收两条信号线。当时钟输入为低电平时，到从站的两条输入线被拉高。这将打开两个晶体管，并将输入预充电到从站。当时钟进行高转换时，主级中的上拉晶体管被截止，从而将从级的输入与主级的输出分离。此时，如果数据输入为高电平，则从站的A输入将被释放。如果数据输入为低电平，则从站的B输入将被释放。在从站的两个输入与主站分离之后，数据输入信号的任何变化都会导致从站的输入浮动为低电平，因为两个线路不被拉高或低电平。以这种方式，从站的输入在每个时钟周期进行预充电和放电。这种预充电导致几乎为零的设置时间。
