Design of 250-Mb/s Low-Power Fiber Optic Transmitter and Receiver ICs for POF Applications

Abstract

This paper describes 250-Mb/s fiber optic transmitter and receiver ICs for plastic optical fiber applications using a 0.18-Jlm CMOS technology. Simple signal and light detection schemes are introduced for power reduction in sleep mode. The transmitter converts non-return-to-zero digital data into 650-nm visible-red light signal and the receiver recovers the digital data from the incident light signal through up to 50-m plastic optical fiber. The transmitter and receiver ICs occupy only 0.62 mm
