Abstract :
A fourth-order filter incorporates a method of suppressing interferers without filtering the desired signal, relaxing the trade-offs between noise, linearity, and power dissipation. Designed for the baseband of a 2.4 GHz receiver and fabricated in a 0.25 μm CMOS technology, the filter exhibits an input-referred noise of 17 nV/√(Hz) while dissipating 2 mW from a 2.5 V supply and the receiver achieves a noise figure of 6 dB with a power consumption of 17.5 mW.
