    摘要: Provided is a low-power wireless communication apparatus and method. In the apparatus, a low-noise amplifier amplifies an RF signal in an on state, the low-noise amplifier be turned on/off according to a predetermined control signal. A wake-up signal detector detects a wake-up signal from the amplified RF signal. A controller provides the predetermined control signal such that the low-noise amplifier and the wake-up signal detector operate at a predetermined on-off duty ratio in a sleep mode corresponding to an Rx waiting state, and switching to an Rx mode to maintain the on state of the low-noise amplifier when the wake-up signal is detected.

    摘要: A super-regenerative receiver including a super-regenerative oscillator is disclosed. The super-regenerative receiver includes a super-regenerative oscillator for generating an oscillation signal when receiving driving current exceeding a predetermined critical level. The receiver also includes a bias current controller for generating bias current according to an output of the super-regenerative oscillator, and a pulse width controller for receiving a predetermined clock and controlling a width of the clock according to the output of the super-regenerative oscillator. The super-regenerative receiver further includes a quench generator receiving the width-controlled clock from the pulse width controller and generating quench current that varies according to the pulse width of the clock. The driving current for oscillation equals to a sum of the bias current N-times multiplied and the quench current.

    摘要: Disclosed is a wake-up system with passive correlators, adopted to wireless transmission/reception devices such as remote controllers, mobile communication terminals, etc. The wake-up system includes a transmitter and receiver. In the transmitter wake-up signals and delayed wake-up signals delayed by a predetermined delay time are correlated and coded, respectively, for transmission. In the receiver, signals transmitted from the transmitter and signals delayed by the predetermined delay time are correlated and decoded, respectively. The decoded signals are converted into DC switching voltage VSW for a switching operation of power, thereby performing a wake-up operation. The wake-up system with passive correlators can reduce consumption power for wake-up operations in a receiver such that correlation operations of a correlator including passive electrical elements such as a matched filter, etc. are performed at a transmitter and the receiver in the same fashion and wake-up signals are transformed into a signal for performing the wake-up operation in the receiver.
