Ultralow-power CMOS/SOI Circuit Technology
We have introduced an example of a system that embodies the concept of a ubiquitous communication service and explained the importance of low power consumption in the communicator that will serve as the bridge between the real world and the network for real-time services in which sensor data is acquired every second. An effective solution to the problem of high energy efficiency is to employ the synergy of combining low-voltage analog circuit technology and FD-SOI devices. Taking advantage of that synergy to reduce the power consumption of the communicator during operation to about 10 mW and employing intermittent operation with an activity rate of less than 1% would make it possible to support operation for one year or more with a commercial coin-type lithium battery.
