|---|---|---|
This paper presents a multiband reconfigurable low noise amplifier (LNA) based on dual-feedback common-gate (CG) configuration. The input impedance of the LNA is tuned synchronously with output load due to the reflection of load impedance to input by the proposed source-follower positive feedback method. This method also improves the stability of the LNA, which is an issue in conventional positive feedback methods. In addition, both the source-follower positive feedback and the negative feedback by capacitor cross-coupling help to reduce noise figure. Fabricated in TSMC 0.18 mu m CMOS process, measurement results show the LNA is reconfigurable from 1.833GHz to 2.47 GHz, with S11 automatically centered with S21. It achieves a power gain from 15 to 17.4 dB, 1.62 dB minimum NF, and -4.4 dBm maximum IIP3. 10.5 mA current is consumed from 1.8 V supply. |
