摘要

Loop delay degrades the accuracy of the traditional peak detectors and limits operational frequency to 1 MHz or less. This paper proposes a delay time compensation scheme boosting operational frequency to 20 MHz while delivering high-accuracy measurements of the peak voltage. The proposed peak detector is implemented using TSMC 0.18 mu m CMOS process requiring only 1.05363 mm(2). The new approach doubles measured performance over standard peak detectors.
