Abstract
The device for measurement of current exchanged between a battery ( ) and electrical circuits ( ) of a portable telephone includes a current sensor ( ), connecting the battery ( ) to the circuits ( ), connected to a first input ( ) of first integrating circuits ( ), integrating the current measurement and controlling a comparator ( ) detecting the crossing of a high threshold (Vs+) through the integral of the current and applying to a second input ( ) of the first integrating circuits ( ) a calibrated feedback signal to recall below the high threshold (Vs+), second integrating circuits ( ) to integrate the feedback signals, providing a measurement of the current exchanged. The invention applies well to mobile telephones.
