Abstract

The paper presents a V-band Low Noise Amplifier (LNA) utilizing Grounded Coplanar Waveguide (GCPW) technology, known for its high linearity, low noise figure, and low power consumption. It examines various transistor finger width to gate width ratios to optimize transistor performance, concluding that a common source (CS) topology with a 3 μm transistor gate width offers superior performance due to enhanced current density. To improve linearity, a third-order transconductance cancellation technique is used to offset the negative gm3 value in the three-stage LNA design. The amplifier achieves a gain of 10.7 dB and a measured noise figure (NF) of 3.7 dB, while consuming 6.8 mW of power from a 1-V supply in high linearity mode. The LNA die, with pads included, measures 0.59 × 0.59
