  • Methods and apparatus for peak-voltage measurement of AC signals
    Patent number: 10107841
    Abstract: In described examples, an apparatus includes: an input terminal for receiving an alternating current voltage signal; a clamping circuit coupled to the input terminal outputting a clamped voltage signal that is constrained in magnitude; a first comparator coupled to the clamped voltage signal outputting a first compare signal when the clamped voltage signal is a positive voltage that exceeds a positive threshold; and a second comparator coupled to the clamped voltage signal outputting a second compare signal when the clamped voltage signal is a negative voltage that exceeds a negative threshold. The apparatus includes a timer circuit coupled to the first and second compare signal outputting a time duration signal corresponding to a time between the first and second compare signals; and a logic circuit coupled to the time duration output signal determining a peak voltage of the alternative current voltage signal responsive to the time duration output signal.
