Abstract
A system having a signal converter device, and a method for operating a system having a signal converter device is disclosed. One embodiment provides loading a capacitive device to a preparation voltage in a first operating phase, and loading the capacitive device to a measuring voltage in a second operating phase after the first operating phase.
Claims25
A method for operating a system having a signal converter device, comprising:
- loading a capacitive device to a preparation voltage in a first operating phase;
- and
- loading the capacitive device to a measuring voltage in a second operating phase after the first operating phase,
- wherein the preparation voltage is outside an expected measuring range of a sensor to be connected to the signal converter device.
1 more element
A system having a signal converter device, comprising:
- a capacitive device;
- and
- a first switch and a second switch configured to couple the capacitive device to a preparation voltage;
- wherein the preparation voltage is outside an expected measuring range of a sensor to be connected to the signal converter device.
1 more element
A system having a signal converter device, comprising:
- a capacitive device;
- a first switch associated with a first pin or pad to couple the capacitive device to a preparation voltage;
- and
- a second switch associated with a second pin or pad different from the first pin or pad to couple the capacitive device to a measuring voltage,
- wherein the preparation voltage is outside an expected measuring range of a sensor to be connected to the signal converter device.
2 more elements
A system having a signal converter device, comprising:
- a capacitive device;
- and
- first means for switching and second means for switching configured to couple the capacitive device to a preparation voltage,
- wherein the preparation voltage is outside an expected measuring range of a sensor to be connected to the signal converter device.
