This paper presents a design of a reconfigurable low noise amplifier (LNA) for multiband orthogonal frequency division multiplexing (MB-OFDM) ultra wideband (UWB) receivers. The proposed design is divided into three stages; the first one is a common gate (CG) topology to provide the input matching over a wideband. The second stage is a programmable circuit to control the mode of operation. The third stage is a current reuse topology to improve the gain, flatness and consume lower power. The proposed LNA is designed using 0.18 μm CMOS technology. This LNA has been designed to operate in two subbands of MB-OFDM UWB, UWB mode-1 and mode-3, as a single or concurrent mode. The simulation results exhibit the power gain up to 17.35, 18, and 11 dB for mode-1, mode-3, and concurrent mode, respectively. The NF is 3.5, 3.9, and 6.5 and the input return loss is better than −12, −13.57, and −11 dB over mode-1, mode-3, and concurrent mode, respectively. This design consumes 4 mW supplied from 1.2 V.

An ultra-wideband (UWB) low noise amplifier (LNA) for 3.3–13.0 GHz wireless applications using 90 nm CMOS is proposed in this paper. The proposed LNA uses an improved common-gate (CG) topology utilizing feedback body biasing (FBB), which improves noise figure (NF) by a considerable amount. Parallel-series tuned LC network was used between the common-gate first stage and the cascoded common-source (CS) stage to achieve the maximum signal flow from CG to CS stage. Improved CS topology with a series inductor at the drain terminal in the second stage connected and cascoded CS third stage provides high power gain (S21) and bandwidth enhancement throughout the complete UWB. A common-drain buffer stage at the output provides high output reflection coefficient (S22). It achieves an average power gain (S21) of 14.7 ± 0.5 dB with a noise figure (NF) of 3.0–3.7 dB. It has an input reflection coefficient (S11) less than −11.7 dB for 3.3–13.0 GHz frequency and output reflection coefficient (S22) of less than −10.6 dB with a very high reversion isolation (S12) of less than −72.4 dB. It consumes only 5.2 mW from a 0.7 V power supply.
