A 0.5-V 320 μW CMOS MedRadio receiver RF front-end with a current-reuse gw-boosting common gate low noise amplifier

Abstract

In this paper, an ultra-low-power medical device radiocommunications service (MedRadio) receiver RF front-end employing a current-reuse gm-boosting common-gate low noise amplifier (CGLNA) is proposed. The proposed current-reuse gm-boosting CGLNA has larger voltage gain and lower NF characteristics than a conventional gm-boosting CGLNA with the same power consumption. The RF front-end, implemented in a 0.13 μm CMOS process, consumes 320 μ W from a 0.5-V supply voltage. It achieves a conversion gain of 37 dB, NF of 3.4 dB, S11 of less than −10 dB, and an IIP3 of −34 dBm.
