METHODS AND APPARATUS TO DETERMINE A FREQUENCY OF A SIGNAL

Abstract: an example apparatus includes: comparison circuitry configured to determine first and second frequencies from a plurality of clock count ranges and a clock count value, the plurality of clock count ranges each having a range of possible count values corresponding to possible frequencies, the first and second frequencies correspond to the clock count ranges that include the clock count value; comparator circuitry configured to generate a temperature indication based on a comparison of a temperature voltage to a reference temperature voltage; and overlap determination circuitry configured to select one of the first or second frequencies based on the comparator circuitry.
