8.2.2 Detailed Design Procedure

When the focal constraint is the battery life, the selection of a low power voltage regulator and low leakage MOSFET to power gate the µC is mandatory. The first step in the design is the calculation of the power consumption of each device in the different mode of operations. An example is the HDC1000, in measurement mode the RF micro is in normal operation and transmission. The different modes offer the possibility to select the appropriate time interval which respect the application constraint and maximize the life of the battery.
