    Abstract: A device and method for automatically controlling power of a radio mobile terminal connected to a hands-free kit and for preventing the radio mobile terminal from malfunctioning. In a power control method for automatically turning on a radio mobile terminal connected to a hands-free kit, the radio mobile terminal including a power control signal generator, a signal output terminal and a signal input terminal, the hands-free kit including a power-on signal generator and a signal detector, a power-on signal is supplied to the signal input terminal for a predetermined time period through the power-on signal generator when the radio mobile terminal is connected to the hands-free kit. After the predetermined time period elapses, generating the power-on signal is stopped. It is determined if the driving signal generated by the signal output terminal is detected through the signal detector. If the driving signal is detected, generating the power-on signal is stopped.

    Abstract: A delay-locked loop (DLL) circuit includes a standby signal generating circuit, a front stage circuit, and a back stage circuit. The standby signal generating circuit generates a first standby signal and a second standby signal in response to an active signal, a crock enable signal, a first column address strobe (CAS) latency signal, and a second CAS latency signal. The front stage circuit compares the phase of an external clock signal and the phase of a feedback signal and delays the external clock signal based on the phase difference between the external clock signal and the feedback signal to generate a first clock signal. The back stage circuit executes interpolation and duty-cycle correction on the first clock signal.

    Abstract: A data output buffer includes an output terminal, a buffer and a pull-down driver. The output terminal is coupled to a first end of a transmission line, the transmission line being coupled to a pull-up termination resistor at a second end. The buffer pulls up the output terminal to a first power supply voltage and pulls down the output terminal to a second power supply voltage based on an output data signal. The pull-down driver pre-emphasizes an initial stage of a pull-down driving operation of the output terminal based on the output data.
