Abstract: PURPOSE: A rectifier, a received signal strength indicator using the same, and a receiver using the same are provided to improve linearity although a low voltage is supplied. CONSTITUTION: A received signal strength indicator(RSSI) includes six differential amplifiers, seven full wave rectifying circuits, a secondary low pass filter, and a DC offset cancelling unit. The six differential amplifiers form an amplifier chain. The six differential amplifiers amplify output signals of two band pass filters. One full wave rectifying circuit rectifies differential signals outputted by the two band pass filters. Six full wave rectifying circuits respectively rectify differential signals outputted by six differential amplifiers. Output signals of seven full wave rectifying circuits are merged by the secondary low pass filter and are filtered to generate a display voltage such as DC.

Abstract: PURPOSE: A channel selection method and communication method are provided to convert a communication channel by sensing wireless interference from a Zigbee sensor network. CONSTITUTION: An interference sensing process is repeated(205). When interference is sensed, a channel hopping method is executed by considering a Wi-Fi channel in a current channel. It is determined whether a channel is available(211). When the available channel is not searched, a hopping sequence interval is controlled(215). It is searched whether the channel is available. When the available channel is searched, the available channel is used for communication. [Reference numerals] (205) Interference sensed?; (AA,CC,EE,KK,HH,II,OO,PP) No; (BB,DD,FF,GG,LL,JJ,MM,NN) Yes

Abstract: A super regenerative receiver and a method for saving power in a super regenerative receiver are provided to adjust a duty cycle rate to reduce average power consumption to periodically turn off power of the super regenerative receiver, thereby reducing average power of the receiver. An operation time for oscillation is changed according to whether an input signal exists in an oscillator(530). A power controller(510) applies power to an isolation amplifier(520), the oscillator, an envelope detector(540) and amplifier(550) only during a period when the oscillator operates.
