Abstract

The ZigBee technology based on IEEE 802.15.4 is widespread use of biomedical applications providing wireless networks. A fully integrated low-power 2.4GHz ZigBee transceiver implemented in CMOS technology is demonstrated. It has RF and analog front-ends, a frequency synthesizer, and digital modulator and demodulator compliant to IEEE 802.15.4. The direct-modulation using fractional-N synthesizer is adopted as transmitter architecture. The transmitter provides high output power of +9dBm and excellent EVM of 5.1%. The direct conversion architecture uses in receiver. Receiver sensitivity is -97dBm. Current consumption for continuous TX transmission at +9dBm output power is 28.2mA and for continuous RX reception is 16mA. Excellence coexistence performance is presented by studying WLAN interferer rejection.
