Abstract :
A burst-mode laser driver for passive optical networks (ATM-PON/FSAN, N-PON, π-PON) uses mixed-signal design techniques in digital 0.5-μm CMOS process. Power consumption is 15 mW, which is about an order of magnitude less than previous designs. The laser driver features automatic power control and laser end-of-life detection. These features are implemented with a novel peak comparator, which operates on a packet-by-packet basis
