A low power UWB-LNA using active dual loop negative feedback in CMOS 0.13µm

摘要

across the entire band. The LNA is composed of a voltage amplifying negative feedback amplifier with a transconductance amplifier forming a shunt-shunt feedback around it, thereby tailoring the input impedance with respect to the gain settings of the first amplifier. The values of the resistive feedback elements have been chosen such that they fulfill the requirements of gain, input impedance, noise figure and linearity. The design has been carried out in TSMC 0.13 mum CMOS technology. From circuit simulations, the average gain of the LNA across 2-7 GHz is 13 dB. The noise figure is below 4 dB with a minimum of 2.9 dB. S
