    • A transceiver circuit having 10 mb and 100 mb transmit and receive circuitries using the power saving methods of the present invention is disclosed. The power consumption of the transceiver circuit can be significantly reduced by providing each defined subcircuit with its own power supply and means of activation and deactivation. However, the method for activating and deactivating digital subcircuits and analog subcircuits are different and therefore different types of control signals and methods are provided. Furthermore, there are two general types of power-saving situations. The first type is near total circuit power-down and the second type is partial circuit power-down. The present invention in yet another embodiment discloses a method for minimizing energy usage during idle period.
    • 公开了使用本发明的省电方法的具有10mb和100mb发送和接收电路的收发器电路。 通过为每个定义的子电路提供自己的电源和激活和停用的手段,可以显着减少收发器电路的功耗。 然而,用于激活和停用数字子电路和模拟子电路的方法是不同的,因此提供了不同类型的控制信号和方法。 此外,省电情况有两种。 第一种类型是接近总电路掉电,第二种是部分电路掉电。 在另一个实施例中的本发明公开了一种在空闲时段期间最小化能量使用的方法。
