Abstract
A three-stage common-source low noise amplifier (LNA) is designed in a 65 nm LP CMOS process. Basically, at mm-wave frequency the Miller capacitance degrades the amplifier performance dramatically. To address these issues, a transformer based neutralization technique is used. With the proposed technique, simulations show that the circuit achieves a gain of 22 dB along with a 1-dB bandwidth of 4 GHz. The noise figure is 5.5 dB and the IIP3 is -10.7 dBm with a power consumption of 26 mW from a 1.2 V supply.
