集成电路中的电压检测电路以及产生触发标志信号的方法
摘要：
一种集成电路，其包含用于产生触发标志信号的至少一个隧穿装置电压检测电路。隧穿装置电压检测电路包含第一与第二分压器，其接收供电电压并具有对应的相应第一与第二内节点输出电压。第一与第二分压器被配置为使得第一输出电压相对于供电电压是线性的，并使第二输出电压相对于供电电压是非线性的。随着供电电压逐渐上升，第一与第二输出电压的曲线在特定电压处交叉。运算放大器电路检测第一与第二输出电压何时变得相等，并对之做出响应地输出表示供电电压已达到某个等级的触发信号。
摘要（英）：

An integrated circuit that includes at least one tunneling device voltage detection circuit for generating a trigger flag signal. The tunneling device voltage detection circuit includes first and second voltage dividers receiving a supply voltage and having corresponding respective first and second internal node output voltages. The first and second voltage dividers are configured so the first output voltage is linear relative to the supply voltage and so that the second output voltage is nonlinear relative to the supply voltage. As the supply voltage ramps up, the profiles of the first and second output voltage cross at a particular voltage. An operational amplifier circuit senses when the first and second output voltages become equal and, in response thereto, outputs a trigger signal that indicates that the supply voltage has reached a certain level.
