The Design Of UWB-NFC Component Interconnect Rf Receiver SOC Chip

UWB Near Field Communication(UWB-NFC) is still in the initial stage of development in China. UWB wireless communication has special superiority in low cost short/middle distance wireless communication(such as NFC) for the features of low power spectrum and high energy efficiency. Ultrashort wireless communication within a meter and Wireless Access will become more necessary while the demands of Ultrashort wireless communication has been increasing with the popularization of wired access.This research is supported by the National High Tech (863) Program of China (No. 2007AA01Z2b3), which is UWB SOC Chip Design and Network Experiment Research relying on Shenzhen Graduate School of Tsinghua University. According to requirements of the project, a high speed SOC chip for wireless components interconnected between electronic equipments at NFC channel without considering multi-path effect should be achieved.The system adopts a novelty non-coherent measure to receive UWB RF signal in 3~5GHz and 250Mbps symbol rate. The system has features of low complexity, low consumption, low cost, high speed and high stability. The project is novel which has special application value.In this paper, several existing technology of receving UWB signal was analyzed. A novelty non-coherent receiving technology was adopted. Algorithm of the project was designed which had been simulated by Matlab software to validate the feasibility. The frame of the system of the chip was designed to allocate the voltage level gain, calculate the noise figure and configure capability of export drive, etc. The chip's total system circuit and the layout design were achieved in 0.18 um RF CMOS standard process under 1.8V operating voltage.The post-simulations results using Cadence Spectre simulation indicates that the proposed chip achieved input matching of wide-band range, small noise figure, broadband linearity performance and excellent PSRR performance. It can be used in 3~5GHz UWB Near-field Communication system which meets the demands of low-power, high-performance electronic systems with a good application value. The circuit and layout approved by Shenzhen Graduate School of Tsinghua University had been sent to tap out.
