The design and analysis ofa reconfigurable dual-band down-conversion mixer for IMT-advanced (3.4-3.6 GHz) and UWB (4.2-4.8 GHz) applications are presented.Based on a folded double-balanced Gilbert cell,which is well known for its low voltage,simplicity and well balanced performance,the mixer adopts a capacitive cross-coupling technique for input matching and performance improvement.Switched capacitors and resistors are added to shift the working bands.Fabricated in a TSMC 0.13 μm process,the test results show flat conversion gains from 9.6 to 10.3 dB on the IMT-A band and from 9.7 to 10.4 dB on the UWB band,with a noise figure of about 15 dB on both bands.The input third-order intercept points (IIP3) are about 7.3 dBm on both of the frequency bands.The whole chip consumes 11 mW under 1.2 V supply and the total area of the layout is 0.76 × 0.65 mm2.
