| 摘要 |
The device (10) of the invention includes a data acquisition and processing line (12) comprising a first member (14) for the acquisition of a first parameter supplied with a voltage determined by a difference between an electric power source potential (VA) and a potential (VB) higher than the source potential (VA), the higher potential (VB) being supplied by a first supply member (16). The line further includes a clock (28) for synchronising the activation signal of a driver member (30) of the first supply (16) and acquisition (14) members. The clock (28) and the driver member (30) are supplied with a voltage determined by a difference between, on the one hand, an intermediate potential (VC) provided by a second supply member (32) and situated between the source potential (VA) and a ground potential (VM) and, on the other hand, the ground potential (VM). |
