Abstract: PROBLEM TO BE SOLVED: To provide a system for protecting a weak device operated in a micro-electronic circuit inclusive of a high voltage electric power supply from excess stress caused by a high voltage.
SOLUTION: This system prevents a weak device from failing during an increase in output, during a decrease in output, and when a low voltage electric power supply is absent in a multiple electric power supply system. This system is provided with a circuit for detecting a low-voltage electric power supply configured to detect an increase in output of a circuit, a decrease in output of a circuit, and when a low-voltage electric power supply is absent and generate a control signal after the detection. This system further has a controllable current mirror device configured to supply a trickle current during an increase in output of a circuit, during a decrease in output of a circuit, and when a low-voltage electric power supply is absent, in response to a control signal received from the circuit for detecting a low-voltage electric power supply, to maintain a conductive channel of the weak device.

Abstract: A data communication system (900) includes a transmitter unit (100) and a receiver unit (200). The transmitter unit (100) has a transmission characteristic that is adjustable in accordance with equalization information. The transmitter unit (100) is operable to transmit a predetermined signal and the receiver unit (200) is operable to receive the predetermined signal. The receiver unit (200) is further operable to generate the equalization information by examining the eye opening of the received signal, and transmit the equalization information to the transmitter unit (100).

Abstract: 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.
