Abstract :
An ultra-low-power 401-406 MHz Medical Device Radiocommunication Service (MedRadio) receiver RF front-end for biomédical telemetry applications is implemented using 0.18-μm CMOS technology with a 1-V supply voltage. The receiver RF front-end employs the proposed complementary current-reuse low-noise amplifier (CCRLNA) which shows enhanced noise and linearity performance in comparison to the well-known source degeneration cascode LNA at equal power consumption and design conditions. The RF front-end including the proposed CCRLNA, transconductor, I/Q folded mixer, and LO buffers achieves a conversion gain of 28.7 dB, NF of 5.5 dB, and IIP3 of -25 dBm while consuming less than 500μ W from a 1-V supply voltage and occupying 0.7mm2 of core die area.
