Abstract
A circuit can include a signal section that includes a first signal transistor configured to operate in a subthreshold region to maintain the signal node at about VCC as VCC rises from a low level; a high threshold section that enables a current path from the signal node to the low power supply node only after a voltage at the detect node exceeds a level greater than a threshold voltage (Vt); and an output section having transistors with relatively long channels, for reduced crowbar current.
