A 2.5 Gb/s CMOS Burst-Mode Limiting Amplifier for GPON System

A 2.5Gb/s burst-mode limiting amplifier for gigabit passive optical networks (GPON) is presented in this paper. A multistage architecture with a feedforward automatic threshold control (ATC) circuit is used for quick response. A response time of 5ns and sensitivity of 4 mVpp1 is achieved by introducing a modified ATC circuit and a modified amplified stage with active feedback and negative Miller capacitance compensation techniques. This chip operating with a supply voltage 1.8 V is fabricated in 0.18mum CMOS technology. Its die size is 1.1 times 1 mm2.
