Abstract
A reference generator having a temperature-dependent output variation that is greater than an absolute temperature variation includes a first source and a second source, the first source generating a proportional to absolute temperature (PTAT) output. The second source generates an output having a temperature coefficient less than or equal to zero. The reference generator further includes a subtraction circuit coupled to the first and second sources, the subtraction circuit operatively subtracting the output of the second source from the PTAT output and generating an offset output, the offset output having a variation greater than an absolute temperature variation. Using the reference generator described herein in accordance with the invention, circuits having a relatively high temperature dependency can be easily compensated. Moreover, the reference generator is suitable for temperature sensing with large temperature dependency without requiring a high supply voltage.
