Abstract :
The proposed SUN OFDM-based RF CMOS transceiver, with replacement of ZigBee, can be used as not only an energy saving intelligent green home, which is related to Smart Grid, but also an universal remote controller, a Building Automation, and so on. With our proposed SUN OFDM RF transceiver, wireless connectivity among CEs (Consumer Electronics) devices and electric meters can save electronic energy and make lives more comfortable. The proposed RF transceiver consists of a RF front-end, a TX BBA (Base Band Analog), a RX BBA, and a PLL. Re-using of a LC resonator in the RF front-end can reduce the chip size of RF transceiver, DC power consumption, and the cost. The proposed RF transceiver is implemented in a 0.18-μm CMOS technology and consumes 37-mA in TX and 38-mA in RX mode from a 1.8-V supply voltage. In addition, with a fabricated RF transceiver chip, we have succeeded a public demonstration.
