A 2.4-GHz CMOS short-range wireless-sensor-network interface for automotive applications

摘要

This paper describes a CMOS interface for shortrangewireless sensor networks (CMOS-SRWSN interface). Thesensor interface is composed of a sensor readout, electronicsfor processing and control, a memory, a radio-frequency CMOStransceiver for operation in the 2.4-GHz industrial, scientific, andmedical bands, and a planar antenna. The receiver has a sensitivityof −60 dBm and consumes 6.3 mW from a 1.8-V supply. Thetransmitter delivers an output power of 0 dBm with a powerconsumption of 11.2 mW. The application of the CMOS-SRWSNinterface is in the automotive industry for the reduction of cablesand to support the information, communication, and entertainmentsystems in cars..
