Abstract:
An ultra-wideband low-noise amplifier (LNA) is designed for software-defined radios (SDR). Noise-cancellation common-gate stage is combined with capacitive cross coupling for wideband input impedance matching and small noise figure (NF). T-coils and inductive peaking are employed to extend the output bandwidth and to reject the noise from the loading resistors. Linearization using second-order intermodulation injection is adopted to improve the IIP3. Operated at 1.5 V from 0.8 GHz to 10.6 GHz, the 0.13-mum CMOS LNA measures 16-dB gain, -12 dB S11, 3.4-5.6 dB NF, and 1.6-dBm IIP3.
