    摘要: An impulse generation circuit is provided for generating an impulse using a transmission line. Impulse characteristics of the impulse generation circuit are varied with the length of a transmission line rather than the characteristic variation of various devices used therein. The length of the transmission line is adjusted, such that a width of a generated pulse is adjusted. Because an end of the transmission line is short-circuited, the transmission line length can be easily adjusted on a substrate, and a ringing phenomenon due to re-reflection can be removed using termination impedance.

    摘要: Provided are a terminal performing a wake-up with consumption of low power and a wake-up method performed by the terminal. The terminal includes: a passive filter outputting a correlation signal between a received signal and a reference signal; and a wake-up controller controlling whether to wake up a communication module, using the correlation signal output from the passive filter. Thus, a wake-up signal can be processed using the passive element that does not consume power during its operation. Also, a wake-up of a communication module can be controlled using the result of processing the wake-up signal. As a result, power consumption can be greatly reduced during the wake-up.

    摘要: In a clock noise canceling circuit, a coupler extracts a signal from a clock signal. A filter selects a harmonic component of a preset frequency in the extraction signal from the coupler. A phase shifter phase inverts the harmonic component of the preset frequency from the filter. An AGC amplifier amplifies the phase-inverted harmonic component from the phase shifter. Also, a combiner combines the amplified component from the phase shifter with the clock signal to eliminate the harmonic component of the preset frequency from the clock signal. A power detector detects a power level of the harmonic component of the preset frequency in an output signal of the combiner. Additionally, a controller controls gain of the automatic gain control amplifier based on the power level of the harmonic component detected by the power detector, thereby canceling noises.
