چکیده
A dual band, 5.15GHz-5.35GHz, 2.4GHz-2.5GHz, zeroIF transceiver is fabricated on a 0.18μm CMOS process. The fully integrated synthesizer and VCO achieve an integrated phase error of 0.8 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.

Although attractive as a highly integrated solution, direct conversion architecture suffers from problems such as DC offsets, flicker noise and poor quadrature matching, that are further aggravated by using CMOS technology [1]. Furthermore, the 802.11a standard high bit-rate modes require closely matched I/Q frequency response. To alleviate those limitations, a transceiver topology allowing the...
