摘要: 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 mu m CMOS technologies, the TIAs provide 66 dB Omega in the high gain mode, 57 dB Omega 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 510 mu m x 520 mu m.
