    • An off chip driver circuit includes a pre-driver circuit and a driver circuit. Driver data and enable inputs are decoded in the pre-driver circuit to provide independent inputs to pull up and pull down transistors in the driver circuit. The enable input keeps the driver circuit in the active or high impedance modes. A feedback signal generated by the driver output and the driver enable signals controls an inverter circuit within the driver circuit to provide proper biasing conditions at the gate of the pull up transistor. This feed back provides fast switching times for the driver circuit and prevents gate oxide of all the transistors from being overstressed by the external high voltage signal.
    • 片外驱动电路包括预驱动电路和驱动电路。 驱动器数据和使能输入在预驱动器电路中被解码,以提供独立的输入以在驱动器电路中上拉和下拉晶体管。 使能输入保持驱动电路处于有效或高阻抗模式。 由驱动器输出和驱动器使能信号产生的反馈信号控制驱动器电路内的反相器电路,以在上拉晶体管的栅极处提供适当的偏置条件。 该反馈提供了驱动电路的快速切换时间,并且防止所有晶体管的栅极氧化物被外部高电压信号过载。

    • A method for designing a cell-based ASIC device with multiple power supply voltages is disclosed. An ASIC chip image is made without applying power or ground buses to metal layer M1. All fast or high-power circuits are grouped together into high-power logic blocks and synthesized with high-power circuit macro libraries. All slow or low-power circuits are grouped together into low-power logic blocks and synthesized with low power circuit macro libraries. The associate power and ground buses are applied to metal layer M1 in each of the logic blocks. The logic blocks are placed on the ASIC so that different voltage groups are separated by at least one cell. The ASIC is then routed and tested before the mask is released.
    • 公开了一种用于设计具有多个电源电压的基于单元的ASIC器件的方法。 在不向金属层M1施加电力或接地总线的情况下制造ASIC芯片图像。 所有快速或高功率电路都分组成大功率逻辑块,并与大功率电路宏库合成。 所有慢速或低功耗电路都分组成低功耗逻辑块,并与低功耗电路宏库合成。 相应的电源和接地总线被施加到每个逻辑块中的金属层M1。 逻辑块被放置在ASIC上,使得不同的电压组被至少一个单元隔开。 然后在掩模释放之前,将ASIC路由和测试。
