【 摘 要 】

References(10)This work presents a K band two stage compact CMOS low noise amplifier (LNA) with closely placed two load inductors without guard rings. Unwanted proximate magnetic coupling between load inductors is carefully analyzed and affirmatively used to enhance the gain without impairing the stability. The fabricated compact LNA has a measured peak gain of 15.42 dB at 24 GHz, with the size of 650 µm × 550 µm, and consumes 10.8 mW from 1.2 V supply.
