Abstract :
This letter presents a wideband low-noise amplifier (LNA) that supports both differential and single-ended inputs, while providing differential output. The LNA is implemented in 0.13 mum CMOS technology. For sub-1 GHz wideband applications, this LNA achieves 22.5 dB voltage gain, +1 dBm IIP3, and 2.5 dB NF in the differential receiving mode, while achieving 23 dB voltage gain, -0.5 dBm IIP3, and 2.65 dB NF in the single-ended receiving mode. The LNA core circuit draws 2.5 mA from 1.2 V supply voltage, and occupies a small chip area of 0.06 mm2.
