From the current potential V under degreeDD108 drop to reference potential V0.Decline as the said index of voltage 104.The decline 112
Time constant depends on temperature.The temperature T1, T2Bigger, the current potential 104 is with regard to declining faster.In the integration phase 112
The middle input predetermined measurement moment 114.At the measurement moment 114, the electric capacity is in different temperature T1And T2When have
Different current potentials 116,118.Make the capacitance short-circuit in the reseting stage 122 and the current potential 104 rapidly declines
To zero.
In order to improve sensitiveness, the current potential V can be improvedDD.But, this is by the metal-insulator-halfbody body knot
The limitation of the breakdown voltage of the insulator layer of structure.The voltage in the range of 5V is enough in principle.
