Length가 작아짐에 따라 supply voltage 대비 noise의 비율이 커지는 추세
Presently, the wireless market and the need to develop efficient portable electronic systems have
pushed the industry to the production of circuit designs with low-voltage power supply.
The objective of this work is to introduce an innovative single-stage design structure of low noise
amplifier (LNA) to achieve higher performance under low operating voltage.

5. Conclusions
Expected results of LNA
사용 주파수 대역의 확장을 기대할 수 있다.
RF 회로 소형화 및 비용 절감을 기대할 수 있다.
잡음지수의 개선을 기대할 수 있다.
RF 수신단에서 첫 단의 잡음이 전체 회로의 잡음을 결정하게 되므로 첫 단 LNA의
성능을 향상시켜서 전체 회로의 성능을 향상시킬 수 있다.
