Abstract
A fully integrated low-power high-coexistence 2.4-GHz ZigBee transceiver implemented in 90-nm CMOS technology is demonstrated. The two-point direct-modulation with a fractional-N synthesizer is adopted in the transmitter architecture. The transmitter can provide high output power of + 9 dBm and excellent error vector magnitude of 5.1%. The direct conversion is used in receiver for simplicity and-97-dBm minimum receiver sensitivity is achieved. Current consumptions for a TX at + 9-dBm output power and for an RX are 28.4 and 15.4 mA, respectively. Excellent coexistence is presented through wireless local area network interferer rejection performance.
