Abstract
A peak detector is provided with a comparator and a storage capacitor coupled to the output of the comparator. An analog input signal is supplied via an input capacitor to the inverting input of the comparator. The non-inverting input of the comparator receives an output signal produced by an output buffer arranged in a feedback loop of the comparator. A level shifter is coupled in the feedback loop to dynamically adjust an input signal supplied to the output buffer in accordance with application requirements. The operation of the peak detector is controlled by non-overlapping clock signals supplied to switches at the input and inner feedback loop of the comparator to cancel offset caused by the comparator and output buffer.
