The conventional method of peak detection generally uses an input analog signal directly or a buffered version of this signal to charge a capacitor through a rectifier to a peak signal voltage. This approach for detecting the peak voltage of a signal runs into a number of limitations as the duration of input analog signals decreases. Among these limitations are: analog component saturation, input current, slew rate, band width, output current and voltage limits, rectifier capacitance and switching speed, and capacitor leakages.
