Zusammenfassung:A low-power CMOS RF receiver front-end is proposed for medical device radiocommunications service (MedRadio) applications. The proposed MedRadio receiver front-end design incorporates an AC-coupled current reuse inverter in order to reduce power consumption and increase transconductance g rmm . The proposed RF front-end comprises a current-reuse low noise amplifier with ac coupling inverter topology and an inverter-based single-balanced mixer with complementary switching. The proposed RF front-end is implemented in a 0.18 mu rmm CMOS process and draws 370 mu rmA from a 1 V supply voltage. It shows a gain of more than 29 dB, NF of less than 5.2 dB, and IIP3 of more than - 19.5 dBm for all MedRadio bands.
