Abstract
A sensor may bias a signal to have a characteristic. The characteristic of the signal may depend on a temperature of the sensor such that the characteristic of the signal is outside of a permitted range, associated with the characteristic, when the temperature of the sensor satisfies a temperature threshold. The temperature threshold may be associated with an operating temperature range of the sensor. The sensor may provide the signal having the characteristic.
Claims20
A sensor, comprising:
- one or more components to:
- bias a signal to have a characteristic,
- the characteristic of the signal to depend on a temperature of the sensor such that the characteristic is outside of a permitted range, associated with the characteristic, when the temperature of the sensor satisfies a temperature threshold,
- the temperature threshold being associated with an operating temperature range of the sensor, and
- a temperature dependence of the characteristic, while the temperature of the sensor is outside of the operating temperature range, being greater than a temperature dependence of the characteristic while the temperature of the sensor is not outside of the operating temperature range,
- the temperature dependence being a rate of change in the characteristic per change in temperature of the sensor;
- and
- provide the signal having the characteristic.
