Abstract

This paper proposes a 401MHz-406MHz low noise amplifier for MedRadio applications. The proposed low noise amplifier adopts a common gate amplifier topology using current reuse gm-boosting technique. The proposed low noise amplifier shows better performance of voltage gain and noise figure than the conventional gm-boosted common gate amplifier in the same power consumption. The proposed current-reuse gm-boosted low noise amplifier achieves a voltage gain of 22 dB, a noise figure of 2.95 dB, and IIP3 of -17 dBm while consuming $170{\mu}W$ from a 0.5 V supply voltage in $0.13{\mu}m$ CMOS process.

본 논문에서는 의료 기기용 401MHz - 406MHz MedRadio 대역에서 사용하는 저잡음 증폭기를 제안한다. 제안한 저잡음 증폭기는 전류 재사용 gm-boosting 기술을 이용한 공통 게이트 증폭기 구조를 채택하여 기존의 gm-boosted 공통 게이트 증폭기에 비해 동일한 전력소모에서 더 높은 전압 이득과 더 낮은 잡음 지수 특성을 얻었다. 제안한 전류 재사용 gm-boosted 저잡음 증폭기는 $0.13{\mu}m$ CMOS 공정을 사용하여 설계하였고, 22 dB의 전압 이득, 2.95 dB의 잡음 지수, -17 dBm의 IIP3 특성을 보이며, 공급 전압 0.5 V에서 $170{\mu}W$의 전력을 소비한다.
