  • Patent number: 7801074
    Abstract: Disclosed are a method of controlling packet service setup and a mobile communication system. The method includes the steps of: transmitting a packet service request message containing a requested QoS to a packet service node by a mobile communication terminal; transmitting to the mobile communication terminal a packet service request response message including an assigned QoS determined in consideration of the requested QoS and network resources contained in the message received by the packet service node; comparing one or more parameter values among parameters contained in the assigned QoS contained in the packet service request response message from a mobile communication network with corresponding one or more parameter values among parameters contained in the QoS requested by the mobile communication terminal; and transmitting a packet service cancel request message if a difference between the parameter values is greater than or equal to a preset value.

  • Publication number: 20090298541
    Abstract: A Subscriber Identity Module (SIM) card connector of a mobile terminal is provided. The SIM card connector includes a housing for mounting one or more SIM cards therein, a separation plate separating an internal space of the housing for mounting the one or more SIM cards in a stacked arrangement within the housing and at least one contact point for electrically connecting to at least one of the one or more SIM cards. Thereby, the SIM card connector for mounting two SIM cards in a stacked arrangement enables a dual SIM card mobile terminal requiring 1.5 times more parts than those of a general mobile terminal to effectively utilize available space.

  • Publication number: 20090256733
    Abstract: Provided is a current control circuit. A current control circuit may include a clock sensing unit configured to generate a control signal according to one or more frequencies based on a plurality of clock signals, and a current scaling unit configured to scale a bias current according to the control signal. The current control circuit according to example embodiments may dynamically control a bias current according to one or more frequencies based on a plurality of clock signals so that power consumption of an analog-to-digital converter (ADC) and the semiconductor device including the ADC, which require various operating frequencies, may be improved.

  • Publication number: 20080036522
    Abstract: A level-shifting circuit includes a level shifter and a middle voltage generating unit. The level shifter generates a middle voltage signal by level-shifting a first signal. The middle voltage signal swings between a level of a ground voltage and a level of a middle voltage, and the first signal swings between the level of the ground voltage and a level of a first voltage. In addition, the level shifter generates a second signal by level-shifting the middle voltage signal. The second signal swings between the level of the ground voltage and a level of a second voltage. The middle voltage generating unit generates the middle voltage by receiving the second voltage and the ground voltage. Therefore, the level-shifting circuit increases an operating margin of an input voltage.

  • Publication number: 20060044023
    Abstract: An integrated circuit device includes a differential amplifier having first and second input terminals and at least one output terminal. The first input terminal is configured to receive a reference voltage and the second input terminal is configured to receive a time-varying input signal. A normally-on CMOS transmission gate is also provided. The CMOS transmission gate has an input terminal configured to receive a reference voltage and an output terminal electrically coupled to the first input terminal of the differential amplifier. This CMOS transmission gate operates to reduce fluctuations in the reference voltage caused by kick back noise by adding parasitic capacitance to the first input terminal of the differential amplifier.
