Abstract
A peak detector comprising of a comparator, an input-trigger device, a gate-width control block, an AND gate, a first current source, a second current source, a first switch, a second switch and a capacitor. The peak detector of this invention uses simple circuits to obtain low frequency energy attenuation. The low frequency attenuation can be programmed and hence able to find the actual average voltage peak. In addition, the simple design makes the peak detector of this invention a suitable replacement candidate for the complicated analogue-to-digital converter conventionally used for detecting average energy attenuation after passing through an electric cable. The peak detector can also be used to measure voltage attenuation for signals passing through LAN, transmission medium such as cable or twisted pair or other related products.
