20110001568 | INTEGRATED CIRCUIT WITH LOW TEMPERATURE COEFFICIENT AND ASSOCIATED CALIBRATION METHOD - An integrated circuit (IC) with a low temperature coefficient and an associated calibration method are provided to lower the effect of the environmental temperature on the IC and at the same time to maintain the small area and low power consumption of the IC. The IC includes a first circuit, a second circuit and a calibration control circuit. The first circuit has a low temperature coefficient and generates a first output. The second circuit has a high temperature coefficient and generates a second output. The calibration control circuit detects the first and second outputs, and compares the first and second outputs according to a predefined relationship therebetween so as to generate an adjusting signal. The adjusting signal is for adjusting the second circuit such that the second circuit can have the characteristic of the low temperature coefficient. | 01-06-2011 |

20080250258 | NETWORK PROCESSOR AND ENERGY SAVING METHOD THEREOF - A network processor includes a transceiver circuit, a network data processing unit, and a clock signal control unit. The transceiver circuit transmits and receives a network signal, compares a voltage level of the network signal with a threshold value, outputs a comparison result, and operates under a first clock signal. The network data processing unit is coupled to the transceiver circuit to process the network signal, and operates under a second clock signal different from the first clock signal. The clock signal control unit disables supply of the second clock signal to the network data processing unit when the voltage level is smaller than the threshold value, and enables supply of the second clock signal to the network data processing unit when the voltage level is not smaller than the threshold value. An energy saving method for a network processor is also disclosed. | 10-09-2008 |

20140300397 | CLOCK GENERATOR AND METHOD THEREOF - A clock generation device includes a first delay unit, a frequency divider, an angle delay unit and a first calculating unit. The first delay unit receives an input clock and delays the input clock by a first preset period to generate an input delay clock. The frequency divider divides a frequency of the delay clock to generate a first frequency-divided clock and a second frequency-divided clock. A frequency of each of the first frequency-divided clock and the second frequency-divided clock is a preset multiple of the input delay clock. The angle delay unit delays the first frequency-divided clock by a second preset period to generate a first delay clock. The first calculating unit determines a trigger time of a first edge of a first output clock with reference to voltage levels of the first frequency-divided clock and the first delay clock and determines a falling time of a second edge of the first output clock with reference to voltage levels of the input clock and the first delay clock. | 10-09-2014 |
20140307867 | ANALOG FRONT-END TRANSMITTER AND A CONNECTION METHOD OF AN X-DIGITAL SUBSCRIBER LINE HAVING A PRE-DISTORTION MECHANISM - A Pre-distortion mechanism for transmit path non-linearity in xDSL AFE is disclosed in the present invention. The AFE includes a line driver and a pre-distortion signal generator. The line driver receives an input differential signal and generates an output differential signal. The input differential signal includes a first input signal and a second input signal. The output differential signal includes a first output signal and a second output signal. The line driver receives the first input signal to generate the first output signal and receives the second input signal to generate the second output signal. The pre-distortion signal generator is coupled to input ends and output ends of the line driver. The pre-distortion signal generator generates a pre-distortion signal according to a first difference between the first input signal and the first output signal, and a second difference between the second input signal and the second output signal so as to adjust an output state of the analog front-end transmitter having a pre-distortion mechanism. | 10-16-2014 |
