By switching the input transconductance and the output capacitance, the narrow-band gain and impedance matching are achieved at the 2.4-GHz and the 5.2-GHz frequency bands. Using a standard 0.18- m CMOS process, a compact dual-band LNA with a chip size comparable to a single-band one is realized in the proposed topology for a minimum hardware cost. The fabricated circuit exhibits gains of 10.1 dB and 10.9 dB, and noise figures of 2.9 dB and 3.7 dB at the two frequency bands, respectively. |
