摘要： A WCDMA enabled user equipment device configured to have functions collectively or selectively idle to conserve power. A discontinuous receiver is used to detect and read network messages and report the messages to the computer within the WCDMA enabled user equipment device. The computer then activates functions previously powered down to receive incoming messages for the user of the device. The discontinuous receiver is also used when the device is active to read network messages, freeing a modem of the device to operate on user messaging; and therefore, enhancing user related performance.

摘要： A technique is disclosed for providing a charge pump circuit for phase locked loop (PLL) to reduce mismatch of up/down currents and feed-through of up/down currents to voltage output.
