Abstract :
A zero standby power remote control system used for household appliances is presented in this paper. The system consists of two parts. One is transmitting unit and power amplifier which send RF modulated signal. The other is receiving unit and power management block which recover energy, demodulate the RF signal and control the power switch of the household appliances. Both transmit and receive ends only work during switching process so that the whole system has zero standby power consumption. The chip in transmitting unit is fabricated in 0.18um CMOS technology and occupies a core area of 0.47mm2. It works around 915MHz and has a max output power of OdBm. The total working power consumption of the chip is 16.45mW. The energy recovery block and ASK demodulation block in the receiving unit are verified.
