This work presents a novel RF current-reused front-end with noise cancellation LNA and current-commutating mixer using 0.18 μm CMOS technology. The proposed design is applicable to a wideband receiver that converts a 0.5 - 5.5 GHz RF signal into a zero- or low-IF signal. A fully differential topology is adopted to suppress the even-order nonlinearity and common-mode noise. Additionally, the proposed...
This paper demonstrates a RF receiver front end circuit for multi-band orthogonal frequency division multiple access (MB-OFDM) using standard 0.18um complementery metal oxide semiconductor (CMOS) technology. The receiver front end includes a low-noise amplifier and a down conversion mixer. The proposed LNA uses transistor's intrinsic capacitor Cgd and only one inductor as input matching network to...
