Abstract
In this paper, a wide-band inductor-less LNA for low voltage operation is presented. The input matching is implemented by using a feedback transistor with a resistor terminated to the source to enhance linearity and to reduce noise. Current reuse technique is employed to increase the total transconductance. Under 1V supply voltage and a DC of 5.6 mA, the LNA achieves an average noise figure of 3.2 dB, a maximum voltage gain of 18.6 dB, and 3 dB bandwidth ranges from 0.2-4.5 GHz.
