Patent number: 8250392Abstract: In described embodiments, turn-on time for active portions of an Energy Efficient Ethernet (EEE) device is improved by storing energy in a corresponding capacitor bank through a bidirectional device from a certain node in the device during an active state, continuing to store the energy when the device enters a Low Power Idle (LPI) state, and then allowing the energy to return to the node through the bidirectional device when the device returns to an active state. During active mode, the bidirectional device controls the capacitor bank so as to charge relatively slowly to store energy, and when the device transitions to LPI, the charge is maintained in the capacitor bank. When the device returns to the active state, the bidirectional device allows the capacitor bank to discharge relatively rapidly to the node, thereby improving the turn-on time of the circuit elements coupled to the node.Type: GrantFiled: November 20, 2009Date of Patent: August 21, 2012Assignee: LSI CorporationInventor: Roger Fratti
