Abstract
A timer to provide pulses at a comparator output wherein a frequency of the pulses is dependent on temperature, wherein providing each pulse includes biasing a first input of the comparator at a voltage and operating a transistor in a subthreshold region of operation to change the voltage of the first input of a comparator at a rate dependent upon temperature. The output of the comparator changes state when the voltage of the first input crosses a voltage of a second input of the comparator.
