Abstract
A design structure for 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.
