摘要
In this paper, a novel low-power multirate architecture for an IF digital frequency downconversion process is presented. The architecture design is the combination of 4-IF oversampling technique and multistage interpolated finite impulse response (IFIR) filter design based on multirate algorithm. It can have very low power dissipation owing to its reduction in hardware complexity and operational frequency. The design example shows that it consumes only 24% power of direct implementation while occupying 26% less area.
