Abstract :
This paper presents a super low power MICS band receiver front-end down converter on 65 nm CMOS for implantable biomedical devices. This down converter, including a LNA and a quadrature mixer, only consumes 500 μA DC current under 1 V supply. With a small LO swing of 300 mV, it provides a voltage conversion gain of 35 dB and a noise figure of 7.4 dB, while a -20 dBm IIP3 is obtained. In order to achieve super low power, current-reuse structure is adopted and all transistors are operated in deep sub-threshold region. Circuits level issues and techniques are also discussed.
