Abstract :
Motivated by the emerging needs for low power narrow-band wireless communication systems, the first micro-power RFIC front-end has been designed using weak inversion CMOS techniques. The front-end, a low-noise amplifier (LNA) combined with a downconversion mixer, has been implemented in a standard 0.8 μm CMOS process. The front-end supply current is less than 110 μA at 3 V supply bias for operation at 450 MHz. High-Q inductors, used in the front-end design, have been manufactured using low-temperature cofired ceramic technology. The front-end´s gain is 25 dB with an IP3 of -15 dBm. This is the lowest current consumption reported to date for a CMOS front-end operating at this frequency
