An IEEE 802.15.4g SUN FSK RF CMOS transceiver for Smart Grid and CEs

The proposed IEEE 802.15.4g SUN FSK (Frequency Shift Keying) RF CMOS transceiver, for the advanced ZigBee, can be adapted to Smart Grid application, but also CEs(Consumer Electronics) Application. With proposed SUN RF transceiver, wireless connectivity among CEs devices and electric meters not only can make lives more comfortable but also save electronic energy. The proposed RF transceiver consists of a digital PLL (Phase Locked Loop), a Driver amplifier, a Modulator, a LNA (Low Noise Amplifier), Complex Band Pass Filter, 3-stage VGA (Variable Gain Amplifier), and Demodulator. The proposed RF transceiver is implemented in a 0.18-μm CMOS technology as a part of SoC and consumes 18~34-mA in TX and 28-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.
