摘要： An integrated circuit (100) has a circuit portion (102) that can be switched to a standby mode through an enable transistor (104), which is coupled between an internal power supply line (120) and an external power supply line (130). The enable transistor (104) is controlled by control circuitry via a control line (160). The control line (160) is coupled to the gates of a first transistor (152) and a further transistor (154) of a logic gate (150). The substrate of the further transistor (154) is coupled to a backbias generator (170). Consequently, when the enable transistor (104) is switched off, the further transistor (154) is enabled and applies a substantial backbias to the gate of the enable transistor (104), thus dramatically reducing the leakage current from the circuit portion (102) through the enable transistor (104).

摘要： A first conductive transistor having a high threshold value and a second conductive transistor having a low threshold value are connected in series between a first actual power supply line supplying a power supply voltage and a virtual power supply line connected to a power supply pin of a circuit block constituted of transistors having a low threshold value. The first and second conductive transistors have polarities which are opposite to each other. A power control circuit turns on the first and second conductive transistors while the circuit block is in operation and turning off the first and second conductive transistors while the circuit block is not in operation. Therefore, subthreshold currents of the first and second conductive transistors can be suppressed. As a result of this, it is possible to reduce power consumption of the semiconductor integrated circuit during its standby period.

摘要： Power supply current, sufficient to power a remote network device, is transmitted concurrently with a network data signal over a transmission line. A power-sourcing network device that can include a coupling circuit provides power and data to the remote network device. The remote network device (which can be a wireless access point) can separate the power signal from the data signal and use the power supply current to further process or retransmit the data signal. The power signal may be a low frequency relative to the frequency of the data signal, or it may be DC.

摘要： In an electronic system with multiple power supplies, a method and apparatus dynamically determines the number of power supplies required to power up the system without overloading any supply. The individual power supplies do not turn on until the determined number of power supplies have received AC power and become operational before attempting a complete system power on. The amount of required power is determined before power up based on the actual power load present. The actual load is determined by sensing load indicators in each load device and computing the total power load. The amount of power from supplies which have received AC power is determined by detecting when AC power has been applied to each power supply and computing the total amount of power available. System power up is delayed when the number of power supplies which have received AC power is insufficient to power the system without an overload situation occurring.
