Abstract: A timer circuit is provided comprising: a resistor; a programmable gain circuit coupled to amplify the reference level based upon a resistor and a selected gain; a detection circuit coupled to identify the amplified reference level based upon a resistor; a selection circuit configured to select the gain based at least in part upon the identified amplified reference level based upon a resistor; a comparator circuit configured to transition between providing a signal having a first value and providing a signal having a second value based at least in part upon comparisons of a reactive circuit element excitation level with the amplified reference level based upon a resistor and with a second reference level; and reactive circuit element excitation circuit configured to reverse excitation of the reactive circuit element in response to the comparator circuit transitioning between providing the signal having the first value and providing the signal having the second value.
