| Abstract: | This paper presents an ultra-low power inductor-sharing 407-425MHz RF front-end （ FE ） chipset for medical applications. The RF FE is composed of the ultra-low power current-reuse LNA PA. By sharing an inductor for both receiver and transmitter, a novel inductor-reuse RF save the use of T/R switch, which saves the cost of chip and meets the requirement of high implemented in a standard 0.18 μ m CMOS process with chip area of 0.43mm2.The powe , Mixer and high-efficient FE structure is proposed to integration. The RF FE is r consumption of RF FE is 0.45mA and 1.53mA, respectively, which demonstrates an ultra-low power, high-integration RF FE |
