摘要/Abstract：
A passive RF signal receiving and power switch ASIC is proposed, designed and verified for remote ac power switch. This IC receives 915MHz RF signals containing power switching commands, and switches on/off the ac power relay of a household appliance accordingly. The proposed ASIC only uses energy recovered from the received RF signal, and it consumes almost zero stand-by current. The wireless identification technique is adopted to improve its anti-disturbance performance. The ASIC is designed in the 0.18μm CMOS process, and it occupies a core area of 0.9mm2. It can work with an RF input power as low as of 40μW, and the data receiving rate is ～25kbps. The measured standby current is less than 10nA. The designed ASIC has been verified in a wireless switch demo system which can be used to switch a 220V AC bulb remotely.
