Design of fully-integrated RF front-end for large image rejection and wireless communication applications

A 2.4GHz image rejection (IR) radio-frequency front-end receiver is proposed in this paper. It adopts double-quadrature architecture with polyphase filters to achieve high image rejection ratio (IRR). A tunable polyphase filter topology that allows counteracting the process spread and frequency drif...

Summary:A 2.4GHz image rejection (IR) radio-frequency front-end receiver is proposed in this paper. It adopts double-quadrature architecture with polyphase filters to achieve high image rejection ratio (IRR). A tunable polyphase filter topology that allows counteracting the process spread and frequency drifts, making it suitable for multi-standards applications, is also dealt with. The IR front-end, implemented in 130nm standard CMOS technology, ensures more than 60dB IRR and good linearity in high frequency applications.
