Abstract
Briefly, embodiments of claimed subject matter relate to comparison of a signal amplitude, such as a signal originating from a battery, for example, with a reference signal. A reference signal may be generated via body-biasing of one or more transistors, for example, which permit operation of the one or more transistors in a sub-threshold state, in which current through the one or more transistors comprises an exponential relationship to an applied voltage. Thus, at least in particular embodiments, detection of low battery voltage or battery overvoltage may be performed utilizing only a very small amount of electrical power.
