Abstract :
A dual band, 5.15GHz-5.35GHz, 2.4GHz-2.5GHz, zero-IF transceiver is fabricated on a 0.18/spl mu/m CMOS process. The fully integrated synthesizer and VCO achieve an integrated phase error of 0.8/spl deg/ at 5GHz. The transmitter achieves -33dB EVM, while the receiver features a 5.2dB noise figure (NF) at 5.25GHz and 3.5dB NF at 2.45GHz. An architecture including feedback paths enables digital calibration, which help eliminate I/Q mismatch and achieve accurately matched baseband filter tuning.
