A RF Transceiver for Wireless Monitoring Systems of the Vertebral Column Behaviour

This paper presents a radio-frequency (RF) transceiver designed, using a standard 0.18 μm CMOS process, for operation in the 2.4 GHz ISM band. The receiver has a sensivity of -64 dBm and consumes 3.5 mW from a 1.5 V supply. The RF transmitter delivers an output power of +11 dBm (15 mW) with a power consumption of 45 mW. These features make the RF transceiver suitable to be integrated in microsystems, where the low-power is a major requirement. The application of these microsystems is to monitoring the influence of heavy loads, in the behaviour of the vertebral column.
