Abstract

This paper presents the design of high sensitivity and wide dynamic range transimpedance amplifiers for burst mode optical receiver. To achieve low noise and wide bandwidth design goals, both Butterworth and Bessel type TIAs are investigated, characterized, and the design techniques for noise optimization are proposed. The conversion gain of TIA is tunable with constant damping factor for wide dynamic range applications. Implemented in a 0.18 urn CMOS technologies, the TIAs provide 66 dBΩ in the high gain mode, 57 dBΩ in the low gain mode, and are capable of operating up to 4.5 Gbps. The measured sensitivity is up to -23.3dBm with 17 dB dynamic range at BER less than 10 -12. Operating under a 1.8 V supply, the power dissipations for Butterworth and Bessel type TIA are about 37.8 mW and 43.2 mW respectively. Chip size is 510μm×520μm.
