Abstract
A temperature sensor and method of temperature sensing is described. A first reference current is provided to a dual-slope ADC during a first slope time duration of a dual-slope ADC conversion cycle. A second reference current is provided to the dual-slope ADC during a second slope time duration of the dual-slope ADC conversion cycle. A digital codeword corresponding to a ratio of the first and second reference currents is then output by the dual-slope ADC. The first and second reference current ratio is related to the temperature.
