This paper presents the design of high sensitivity and wide dynamic range transimpedance amplifiers for a burst mode optical receiver. To achieve low noise and wide bandwidth design goals, both Butterworth and Bessel type TIAs are investigated, characterized, and design techniques for noise optimization are proposed. The conversion gain of the TIA is(More)
This paper describes the design of a 2.5-Gb/s burst-mode optical receiver in a 0.18-mum CMOS process. A dual-gain-mode transimpedance amplifier (TIA) with constant damping factor control is proposed to tolerate a wide dynamic range input signal. By incorporating an automatic threshold tracking circuit (ATC), the TIA and limiting amplifier (LA) are dc(More)
This paper describes the design of a 2.5 Gbps burst-mode optical receiver in a 0.18 mum CMOS process. Integrating both transimpedance amplifier and post limiting amplifier in a single chip, the input sensitivity of the optical receiver is about -18 dBm, and the response time is less than 50 ns. The overall transimpedance gain is 98 dBOmega, and the -3 dB(More)
