摘要: An LED pulse shaping circuit is disclosed which capable of providing improved rise time (using current peaking) and fall charge extraction). The consists a conventional differential switch coupled to pair switching elements resistance elements. A first element activated at the beginning provide for an initially increased drive LED, value used determined level current. peaking thus results in decreasing LED. remaining are utilized, conjunction with switch, reverse flow through end pulse. extraction
