Protocol module of wireless data system dedicated to medical care

A wireless data system is constructed with the use of a SAW-based transmitter and receiver, have been conceived specifically for short range RF link applications. In order to realize the portability as well as to reduce the power consumption, an ASIC architecture is devised to be incorporated with the transmitter/receiver so as to implement the intermittent drive and communication protocol mechanism. By means of a sophisticated drive and protocol mechanism, the wireless data system is applied to the monitoring facilities in medical care. The ASIC module has been implemented by employing 0.6 /spl mu/m three-metal-layer CMOS process. The power dissipation has been lowered to 0.98 mW at 3 V.
