A 3.1–10.6 GHz Ultra-Wideband CMOS Low Noise Amplifier With Current-Reused Technique

Abstract: A 3.1-10.6 GHz ultra-wideband (UWB) low noise amplifier (LNA) utilizing a current-reused technique and a simple high-pass input matching network is proposed. The implemented LNA presents a maximum power gain of 16 dB, and a good input matching of 50 in the required band. An excellent noise figure (NF) of 3.1-6 dB was obtained in the frequency range of 3.1-10.6 GHz with a power dissipation of 11.9 mW under a 1.8-V power supply. The proposed UWB LNA demonstrates the highest power gain and lowest NF among the pub… Show more

“…Resistive feedback is frequently combined with inductive peaking [11,12], and an inductor coupled resonator is sometimes utilized in the feedback loop [13]. The wideband input matching network can also be designed using a high-pass filter [14], where an inputmatching network is devised separately with the cascode amplifier, but the parasitics can lead to a fluctuation of input-matching characteristics. The common-gate configuration can be easily used for wide input impedance matching [15].…”

“…The current-reused architectures with their outstanding trait, i.e. preserving the power consumption, are also used in the UWB design [5]. The noise and distortion cancellation techniques which have been used in [1,2] are going to become the unique trends toward satisfying stringent features of an LNA that are the NF and third-order intercept point (IP3).…”
