摘要： A system for protecting a weak device operating in micro-electronic circuit and a design structure including the system embodied in a machine readable medium are disclosed. The system includes a high voltage power supply from high voltage overstressing prevents the weak device from failing during power-up, power-down, and when a low voltage power supply in a multiple power supply system is absent. The system further includes a low voltage power supply detection circuit configured to detect circuit power-up, circuit power-down, and when the low voltage power supply is absent, and generate a control signal upon detection. The system further includes a controlled current mirror device configured to provide a trickle current to maintain a conduction channel in the weak device in response to the control signal received from the low voltage power supply detection circuit during circuit power-up, circuit power-down, and when the low voltage power supply is absent.

摘要： A design structure embodied in a machine-readable medium used in a design process may include a system for detecting a fault in a signal transmission path. Such system may include, for example, a hysteresis comparator including a latch having n-type field effect transistor (“NFET”) storage elements. The hysteresis comparator may be operable to detect a crossing of a reference voltage level by an input signal arriving from the signal transmission path such that when the comparator does not detect an expected crossing of the reference voltage level by the input signal, the fault is determined to be detected in the signal transmission path.

摘要： In a method for performing equalization of a communication system, a predetermined signal can be transmitted from a transmitter unit to a receiver unit in a downchannel direction on a transmission line, for example as a pair of differential signals which simultaneously transition in opposite directions on respective signal conductors of the transmission line. At the receiver unit, an eye opening of the signal received from the transmission line can be analyzed to determine equalization information. Equalization information can be transmitted from the receiver unit to the transmitter unit in an upchannel direction on the transmission line and be received at the transmitter unit. Using received equalization information, a transmission characteristic of the transmitter unit can be adjusted.
