چکیده انگلیسی
This paper presents two low power UWB LNAs with common source topology. The power reduction is achieved by the current-reused technique. The gain and noise enhancement of the proposed circuit is based on an output buffer which is used by a common source amplifier with shunt-shunt feedback. Chip1 is an adopted T-match input network of 50 Ω matching in the required band. Measurements show that the S11 and S22 are less than â10 dB, and the maximum amplifier gain S21 gives 9.7 dB, and the noise figure is 4.2 dB, the IIP3 is â8.5 dBm, and the power consumption is 11 mW from 1.1 V supply voltage. The input matching of chip2 is adopted from a LC high pass filter and source degenerated inductor. The output buffer with the RC-feedback topology can improve the gain, increase the IIP3, restrain the noise, improve the noise figure and decrease the DC power dissipation. Measurements show 13.2 dB of power gain, 3.33 dB of noise figure, and the IIP3 is â3.3 dBm. It consumes 9.3 mW from 1.5 V supply voltage. These two chips are implemented in a 0.18 μm TSMC CMOS process.
