Control system and management method of a sensor

摘要

The circuit (100) has a sensor block (106) designed to provide a first signal as an output signal and a second signal as a frequency of measured physical quantity, where the frequency is a reference frequency. A control block (102) controls the circuit to allow first and second counting blocks (108, 110) to function according to a first phase in which the counting blocks count and a second phase in which the first counting block counts and the second counting block counts down for which the timing frequency of the second block during the first phase is different from that during second phase. Independent claims are also included for the following: (1) a method for managing a measuring circuit (2) a wearable/portable electronic object.
